This question comes from Sheldon Grimshaw. “I’ve heard that there are more stars in our Universe than there are grains of sand on all the beaches on Earth. Is this possible?” Awesome question, and a great excuse to do some math.
As we learned in a previous video, there are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe – maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe – a 1 followed by 22 zeros. At the high end, it’s 200 sextillion.
These are mind bogglingly huge numbers. How do they compare to the number of grains of sand on the collective beaches of an entire planet? This type of sand measures about a half millimeter across.
You could put 20 grains of sand packed in side-by-side to make a centimeter. 8000 grains in one cubic centimeter. If you took 10 sextillion grains of sand, put them into a ball, it would have a radius of 10.6 kilometers. And for the high end of our estimate, 200 sextillion, it would be 72 kilometers across. If we had a sphere bigger than the Earth, it would be an easy answer, but no such luck. This might be close.
So, is there that much sand on all the beaches, everywhere, on this planet? You’d need to estimate the average volume of a sandy beach and the average amount of the world’s coastlines which are beaches.
I’m going to follow the estimates and calculations made by Dr. Jason Marshall, aka, the Math Dude. According to Jason, there about 700 trillion cubic meters of beach of Earth, and that works out to around 5 sextillion grains of sand.
Jason reminds us that his math is a rough estimate, and he could be off by a factor of 2 either way. So it could be 2.5 sextillion or there could be 10 sextillion grains of sand on all the world’s beaches.
So, if the low end estimate for the number of stars matches the high end estimate for the number of grains of sand, it’s the same. But more likely, there are 5 to 10 times more stars than there are grains of sand on all the world’s beaches.
So, there’s your answer, Sheldon. For some “back of the napkin” math we can guess that there are more stars in our Universe than there are grains of sand on all the beaches of Earth.
Oh, one more thing. Instead of grains of sand, what about atoms? How big is 10 sextillion atoms? How huge would something with that massive quantity of anything be? Pretty gigantic. Well, relatively at least. 10 sextillion of anything does sound like a whole lot.
If you were to make a pile of that many atoms… guess how big it would be. It’d be about…. (gesture big then gesture small) 4 times smaller than a dust mite. Which means, a single grain of sand has more atoms than there are stars in the Universe.

A satellite triplet was born last week. The European Space Agency’s Swarm constellation flew into space on Friday (Nov. 22) on a quest to understand more about the Earth’s magnetic field.
Around the same time, ESA put out a few videos explaining why the magnetic field is important. This one explains that the magnetic field has weakened over the past few years, while the north pole has shifted direction. “In fact, a whole pole reversal is possible,” the narrator says. “It happened last 780,000 years ago at the very beginning of human history. But cavemen didn’t have mobile phone networks, GPS networks or power supplies.”
If a reversal did happen, it could affect those systems, the video adds, asking “Will we soon find ourselves back in the stone age?”
In the short term, however, the focus is on Swarm’s science. The satellites successfully unfurled their booms on Saturday (Nov. 23) and are now starting three months of commissioning before their planned four-year mission.
Once they get going, the satellites will make observations from two altitudes — a pair at about 285 miles (460 kilometers) in altitude and the final of the trio at a higher altitude of 330 miles (530 kilometers). They will monitor any changes in the Earth’s magnetic field, looking at spots ranging from the core of our planet to areas of the upper atmosphere.
Comet ISON joins Earth and Mercury in this photo made by NASA's STEREO-A (Ahead) spacecraft in the early morning hours of Nov. 23, 2013. Click to see additional images.
The day of truth is fast approaching. Will Comet ISON’s sungrazing ways spark it to brilliance or break it to bits? How bright will the comet become? Studying the latest images from NASA’s STEREO Ahead sun-watching spacecraft, it’s obvious that ISON remains healthy and intact. The most recent pictures taken from the ground confirm that no major breakup has occurred. Assuming that ISON doesn’t crumble apart on Nov. 28, when it passes just 730,000 miles (1.2 million km) from the sun, it could brighten to -4 magnitude or better in the hours leading up to and after the moment of perihelion at 12:24:57 p.m. CST (18:24:57 UT).
This beautiful photo of Comet ISON was taken from a mountaintop observatory with a 300mm lens by Juan Carlos Casado of Spain on Nov. 24, 2013. Casado “stacked” or composited four photos to enhance the brightness of the comet against twilight. Click to enlarge.
For comparison, the planet Venus hovers around -4 magnitude and is routinely visible visible with the naked eye in broad daylight if you know exactly where to look. For the sake of establishing a baseline, let’s imagine that ISON will match Venus in magnitude during its crack-the-whip fling around the sun. Naturally, this would put the comet within range of naked eye visibility smack in the middle of the day. Well, maybe. ISON presents us with a little problem. While it may grow bright enough to view in daylight, it will be very close to the sun on perihelion day. Not only will it be difficult to tease from the solar glare, but with the sun only a degree or two away, there’s a real danger you could damage your eyes if you stray too close.
Comet ISON swings rapidly around the sun on perihelion day Nov. 28. Positions are shown hourly with north up and west to the right. Created with Chris Marriott’s SkyMap software
During the early morning hours of the 28th, ISON will lie approximately 2.5 degrees from the sun’s limb or edge. At the time of perihelion that separation narrows to less than 1/2 degree or one solar diameter. This is likely when the comet will shine brightest, but with the sun so close, it will be next to impossible to spot it with naked eye or binoculars at that time. Matter of fact, don’t even try – it’s not worth the risk of damaging your retinas. An expert observer with a carefully-aimed telescope might pick it up, but must use extreme caution that sunlight not enter the field of view. Come sunset, the distance widens again to a somewhat more comfortable 2.5 degrees.
Once, when following Venus as a crescent through inferior conjunction, I dared track it within 2.5 degrees of the sun. THAT was almost too close for comfort. I had to avert my vision from a brilliant wedge of internally reflected sunlight along one side of the view and wear sunglasses to temper the brilliance of the “safe zone” where Venus appeared.. Red and polarizing filters can help reduce glare and increase contrast for near-sun viewing of comets and planets.

In mid-January 2007, Comet C/2006 P1 McNaught had a similar close brush with the sun and peaked around magnitude -5. For several days around perihelion on Jan. 12 it was plainly visible with the naked eye in broad daylight. I spotted it 5.6 degrees from the sun at magnitude -3.5 (twice as faint as Venus) at 10 a.m. on Jan. 13 and 5 degrees from the sun the following day when I estimated its magnitude at -4.5. While close, 5 degrees is a much more comfortable distance for comet and inner planet viewing.
Example using a rooftop to block the sun. When using binoculars for daytime comet hunting, BE SURE you focus them first at infinity otherwise there’s no way to know if the comet will be in focus. I use clouds (the best) or a distant treeline. Credit: Bob King
Whether naked eye, binocular or telescope, the favorite method for finding Comet McNaught in 2007 remains the best for Comet ISON in 2013. Block out the sun by placing something with a crisp edge in its way. Power poles, street lights (finally a good use for them), buildings, roof gables, church steeples and even clouds make ideal sun filters. They effectively remove the sun and allow you to look as close as is safe. Safety is critical here – never look directly at the sun. The damage to your retina will be swift and painless. No comet is worth losing your precious sense of sight.
As Earth rotates, the sun slowly moves across the sky. When using binoculars, if you start to see a bright reflection from approaching sunlight in the field of view, shift your position and re-cover the sun. I’ve been asked if you can simply hold an appropriate solar filter over your eye to dim the sun. Yes you can, but the filter will also completely block your view of the much, much fainter comet. Use the filter instead to dim the sun so you can hunt nearby for the comet.
Use these little pictures to help you know what direction from the sun to look for Comet ISON between 8 a.m. and 2 p.m. CST Thursday Nov. 28. Add one hour for Eastern time; subtract 1 hour for Mountain and 2 hours for Pacific. Be sure to face the direction shown when using the diagrams and completely block the sun from view. StellariumOur final view shows the comet shortly before sunset in the southwestern sky when it lie about 2-2.5 degrees directly above the sun. Time is 4 p.m. CST
Since ISON will be 2.5 degrees from the sun in the early morning and again just before sunset, those might be the best times to find it. Compared to the hour or two around perihelion, the glare will be less though ISON will likely be a little fainter. You can use the diagram above, suitable for mid-northern latitudes, to know in what direction from the sun to look for the comet. If ISON becomes at least as bright as Venus and your sky is deep blue and haze-free, you might just see it on Thursday before sitting down to that Thanksgiving turkey dinner. But of course much depends upon the comet.
Comet ISON will be under constant view Nov. 27-30 in the SOHO coronagraph, an instrument that blocks the sun so scientists can study the near-solar environment. Click to see images. Credit: NASA/ESA
Don’t fret if it’s cloudy. Head over to the Solar and Heliospheric (SOHO) website. There you’ll have a ringside seat Nov. 27-30 as Comet ISON makes its death-defying turn around the sun. Thereafter it will appear risk-free in the morning sky with what we hope will be a beautiful tail.

In just one minute, you can watch the Herschel space telescope painting the sky blue, green and yellow! The colors in this new video represent four years of observations from the European Space Agency telescope, which was active between 2009 and 2013.
“In total, Herschel observed almost a tenth of the entire sky for over 23,500 hours, providing new views into the previously hidden universe, pointing to unseen star birth and galaxy formation, and tracing water through the universe from molecular clouds to newborn stars and to their planet-forming discs and belts of comets,” ESA stated on a video explanation.
As ESA explains, Herschel had two cameras and imaging spectrometers on board, called PACS (Photoconductor Array Camera and Spectrometer, in blue) and SPIRE (Spectral and Photometric Imaging Receiver, in green). When they worked together, their observations are shown in yellow.
Herschel was officially shut down on June 17 — check out the video of those commands here — but the scientific information the telescope produced is still being plumbed by astronomers.

CAPE CANAVERAL, FL – The maiden flight of the Next Generation commercial SpaceX Falcon 9 rocket from the firms Cape Canaveral launch facility is set to soar to space on Monday afternoon, Nov. 25 on a ground breaking mission that will be most difficult ever.
The upgraded Falcon 9 booster is slated to haul the commercial SES-8 telecommunications satellite for the satellite provider SES for SpaceX’s first ever payload delivery to a Geostationary Transfer Orbit (GTO).
Liftoff is scheduled for 5:37 p.m. EST from SpaceX’s Space Launch Complex 40 pad at Cape Canaveral Air Force Station.
Pad 40 is the same location as all prior SpaceX launches from the Florida Space Coast.
SpaceX CEO Elon Musk tweeted that this launch of the Falcon 9 will be the “toughest mission to date.”
This mighty new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. Therefore it can boost a much heavier cargo load to the ISS, low Earth orbit and beyond.
The next generation Falcon 9 is a monster. It’s much taller than a standard Falcon 9 – some 22 stories tall vs. 13 stories.
In anticipation of Monday’s planned liftoff, SpaceX engineers successful completed a wet dress rehearsal and engine hotfire test this past Thursday.
Spectators can view the launch from local public areas, beaches and roads – just as with any other liftoff.
The launch window extends just over an hour until 6:43 p.m. EST.
Weather outlook is 80% favorable at this time but deteriorates in case of a 1 day delay to Tuesday.

SpaceX is planning a live webcast of the launch with commentary from SpaceX corporate headquarters in Hawthorne, CA.
The broadcast will begin at approximately 5:00 p.m. EDT and include detailed discussions about the Falcon 9 rocket, launch and flight sequences as well as about the SES- 8 satellite.
The webcast can be viewed at; www.spacex.com/webcast
The first launch of this next generation Falcon 9 v 1.1 rocket occurred on Sept 29, 2013 on a demonstration test flight from a SpaceX pad at Vandenberg AFB carrying a Canadian weather satellite to an elliptical earth orbit.

SES-8 is a hybrid Ku- and Ka-band spacecraft that will provide communications coverage for the South Asia and Asia Pacific regions.
It was built by Orbital Sciences spacecraft, weighs 3,138 kg (6,918 lbs) and will be lofted to a 295 x 80,000 km geosynchronous transfer orbit inclined 20.75 degrees.

KENNEDY SPACE CENTER, FL – NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) has descended to its planned low altitude orbit and begun capturing science data on its ground breaking mission to study the Moon’s ultra tenuous atmosphere and dust using a spacecraft based on a revolutionary new design aimed at speeding development and cutting costs.
LADEE set sail for Earth’s nearest neighbor during a spectacular night time launch atop the maiden flight of an Air Force Minotaur V rocket on Sept. 6 from NASA’s Wallops Island launch facility on Virginia’s Eastern shore.
The flawless launch thrilled spectators up and down virtually the entire US East coast region and yielded many memorable snapshots.
Following a month long voyage and three and a half long looping orbits of the Earth, LADEE successfully fired its main engine for 4 minutes and 12 seconds on Oct. 6 and successfully entered lunar orbit, Dawn McIntosh, LADEE deputy project manager at NASA Ames Research Center, told Universe Today in an exclusive interview.
A series of engine firings over the past month gradually circularized and lowered LADEE into its final science orbit around our Moon while engineers checked out the spacecraft during the commissioning phase of the mission.
The do or die initial Lunar Orbit Insertion burn (LOI-1) allowed LADEE to be captured into a highly elliptical, equatorial lunar orbit, said McIntosh.

“Two additional LOI burns on Oct. 6 and Oct 9 lowered LADEE to an approximately 4 hour orbit with a periapsis altitude of 234 Kilometers (km) and apoapsis altitude of 250 km” McIntosh told me.
The trio of LOI main engine firings used up most of LADEE’s precious on board fuel.
“LADEE launched with 134.5 kilograms (kg) of fuel. Post LOI-3, 80% of our fuel has been consumed,” said McIntosh.
“Additional orbit-lowering maneuvers with the orbital control system (OCS) and reaction control system (RCS) of approximately 40 seconds were used to get LADEE into the science orbit.
The spacecraft finally entered its planned two hour science orbit around the moon’s equator on Nov. 20.
Its flying at an extremely low altitude ranging from merely eight to 37 miles (12-60 kilometers) above the moon’s surface.
By circling in this very low altitude equatorial orbit, the washing machine sized probe will make frequent passes crossing from lunar day to lunar night enabling it to precisely measure changes and processes occurring within the moon’s tenuous atmosphere while simultaneously sniffing for uplifted lunar dust in the lunar sky.
The remaining fuel will be used to maintain LADEE’s orbit during the approximately 100 day long science mission. The mission length is dictated by the residual fuel available for thruster firings.
LADEE Science Instrument locations
The purpose of LADEE is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface. In turn this will lead to a better understanding of other planetary bodies in our solar system and beyond.
“A thorough understanding of the characteristics of our lunar neighbor will help researchers understand other small bodies in the solar system, such as asteroids, Mercury, and the moons of outer planets,” said Sarah Noble, LADEE program scientist at NASA Headquarters in Washington.
By studying the raised dust, scientists also hope to solve a 40 year old mystery – Why did the Apollo astronauts and early unmanned landers see a glow of rays and streamers at the moon’s horizon stretching high into the lunar sky.
The $280 million probe is built on a revolutionary ‘modular common spacecraft bus’, or body, that could dramatically cut the cost of exploring space and also be utilized on space probes to explore a wide variety of inviting targets in the solar system.
“LADEE is the first in a new class of interplanetary exploration missions,” NASA Ames Director Worden told Universe Today. “It will study the pristine moon to study significant questions.”
“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”
The 844 pound (383 kg) robot explorer was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.
LADEE arrived at the Moon last month in the midst of the US government shutdown – which negatively impacted a host of other NASA missions. Only a ‘skeleton crew’ was available.
“All burns went super well,” Worden told me. And he is extremely proud of the entire team of “dedicated” professional men and women who made it possible during the shutdown.
“It says a lot about our people’s dedication and capability when a skeleton crew’ can get a new spacecraft into lunar orbit and fully commissioned in the face of a shutdown!” Worden said to Universe Today.
Now the real science begins for LADEE and the team.

Comet ISON is heading towards its inexorable close pass of the Sun, which will occur on November 28, 2013. And while we’ve been enjoying great views from astrophotographers, that luxury is probably over as of today, as the comet is just getting to close to the Sun — and its blinding glare — for us to see it. But while we won’t be able to see it from Earth, we’re lucky to have a fleet of spacecraft that will be able to keep an eye on the comet for us! The STEREO spacecraft has already taken images of ISON hurtling towards the Sun; the Solar and Heliospheric Observatory (SOHO) will start observations on November 27. Then, the Solar Dynamics Observatory (SDO) will view the comet for a few hours during its closest approach to the Sun, and the X-Ray telescope on the Hinode spacecraft will view Comet ISON for about 55 minutes during perihelion.
Above is a gorgeous timelapse of ISON from the Teide observatory in the Canary Islands on Nov. 22nd, 2013. See more images and videos below.
Above is a screenshot from the live camera views from the Canada France Hawaii Telescope webcam. You can see a live view from their webcam any time at this link.

As comets ISON and Encke continue toward their respective rendezvous with the Sun, they have now both been captured on camera by NASA’s solar-observing STEREO spacecraft. The image above, taken on Nov. 21 (UT) with STEREO-A’s high-resolution HI-1 camera, shows ISON as it enters the field of view from the left. Encke is at center, while the planets Mercury and Earth (labeled) are bright enough to cause vertical disruptions in the imaging sensors. (The Sun is off frame to the right.)
As cool as this image is, it gets even better: there’s a video version. Check it out below:

It’s fascinating to watch how the solar wind shapes and affects the tail of comet Encke… as ISON moves further into view, I’m sure we’ll see similar disruptions in its tail as well. (And look what STEREO-A saw happen to Encke’s tail back in 2007!)
Encke reached the perihelion of its 3.3-year-long orbit on Nov. 21; newcomer ISON will arrive at its on Nov. 28. While it seems to be holding together quite well in these STEREO images, what happens when it comes within 730,000 miles of the Sun next week is still anybody’s guess.

We’ve seen some great images from the launch of the MAVEN spacecraft earlier this week, but this original drawing of the moment of liftoff of the Atlas V carrying MAVEN is remarkable. This pencil illustration is reminiscent of the early days of spaceflight – or perhaps even the pre-spaceflight days, before we had actual images of launches, only our dreams of spaceflight.
“Everyone takes great photos of the launches and I thought a drawing would be something different,” said artist and photographer Wendy Clark from the UK. “True inspiration comes from the things you love most and I think this is why I especially enjoy drawing space related things.”
Like most of us, Wendy watched the launch online and she started her sketches after NASA started receiving telemetry from MAVEN, and said she worked on the drawing for about 24 hours total since Monday. This final version was done with graphite on A3 paper.
“Don’t let anyone tell you drawing a rocket is easy,” she told Universe Today. “This is only the 2nd drawing I have fully completed of a rocket launch. The special missions always interest me and I’m a fan of Atlas V rocket shapes, although they are not easy subjects to draw!”
Wendy said she’s an avid launch fan, although she’s never witnessed a mission launch in person. “One day would be nice to stand and watch this in person,” she said.
The other launch drawing she completed was of the final launch of the space shuttle program, STS-135, and she said she felt like she got to know the shuttle Atlantis like an old friend.
“When you spend 72 hours drawing a momentous event like this you get kind of attached to the subject in a way you can’t immediately understand,” she said. “I got to know every curve by putting what I saw on paper with graphite.”
