Thanks to a new analysis of pictures obtained by a telescope in Chile, astronomers are gaining a better understanding of how the Milky Way formed and how our home galaxy has changed over the years.
Here’s how the project worked:
– The European Southern Observatory’s Visible and Infrared Survey Telescope for Astronomy (VISTA) 4.1-meter telescope took near-infrared pictures of the bulge of the Milky Way during the Variables in the Via Lactea public survey.
– Using the public data, scientists at the Max Planck Institute for Extraterrestrial Physics (MPE) created a three-dimensional star map of the inner regions of the Milky Way.

– Their findings were that the bulge in the center is shaped like a box or a peanut, with characteristics such as an “elongated bar”. It’s the first time such an accurate 3-D map of the inner universe was constructed, the science team said.
“This indicates that the Milky Way was originally a pure disk of stars, which then formed a thin bar, before buckling into the box/peanut shape seen today,” MPE stated. “The new map can be used for more detailed studies of the dynamics and evolution of our Milky Way.”
Among other conclusions, this helps confirm the fairly recent finding that the Milky Way is a barred spiral galaxy, rather than just a spiral galaxy.

Now’s your big chance to get up close and personal with Vesta, one of the largest asteroids in the solar system.
A new atlas has been released based on 10,000 images from the Dawn mission‘s framing camera instrument, which took the pictures from an average altitude of about 131 miles (210 kilometers). Each map has a scale of 1 centimetre to 2 kilometres (roughly a scale of 0.4 inches : 1.2 miles).
“Creating the atlas has been a painstaking task – each map sheet of this series has used about 400 images,” stated Thomas Roatsch, who is with the German Aerospace Center (DLR) Institute of Planetary Research and led the work.

“The atlas shows how extreme the terrain is on such a small body as Vesta. In the south pole projection alone, the Severina crater contours reaches a depth of 18 kilometres [11 miles]; just over 100 kilometres [62 miles] away the mountain peak towers 7 kilometres [4.3 miles] above the … reference level.”
Astrobotic's model rover explores a mine on Earth to train for lunar lava tunnels (Video screenshot)
Ever since (and most likely long before) the first tantalizing glimpses of a lunar lava tube and skylight were captured by Japan’s Kaguya spacecraft in 2009, scientists have been dreaming of ways to explore inside these geological treasures. Not only would they provide valuable information on the movement of ancient lunar lava flows, but they could also be great places for future human explorers to set up camp and be well-protected from dangerous solar and cosmic radiation.
But before human eyes will ever peer into the darkness of a lava tube on the Moon, robotic rovers will roll along their silent floors — at least, they will if Google Lunar XPRIZE competitor Astrobotic has anything to say about it.
Last month, engineer and Astrobotic CEO Dr. Red Whitttaker talked to NASA about why they want to explore a Moon cave and the history and progress of their project. Check it out below:
“Something so unique about the lava tubes is that they are the one destination that combines the trifecta of science, exploration, and resources.”
– Dr. William “Red” Whittaker, CEO Astrobotic Technology, Inc.
The international Google Lunar XPRIZE aims to create a new “Apollo” moment for a new generation by driving continuous lunar exploration with $40 million in incentive-based prizes. In order to win, a private company must land safely on the surface of the Moon, travel 500 meters above, below, or on the lunar surface, and send back two “Mooncasts” to Earth… all by Dec. 31, 2015.
Astrobotic Technology Inc. is a Pittsburgh-based company that delivers affordable space robotics technology and planetary missions. Spun out of Carnegie Mellon University’s Robotics Institute in 2008, Astrobotic is pioneering affordable planetary access that promises to spark a new era of exploration, science, tourism, resource utilization and mining.

Oh my! We’re not sure to laugh or cry on this one (maybe both). This frog gives new meaning to “flying leap,” (or giant leap). This little guy was obviously startled by the ignition of the Minotaur V rocket that launched the LADEE spacecraft last Friday.
We’ve confirmed this image is in fact an actual photo taken by one of NASA’s remote cameras set up for the launch on September 6, 2013 from the Wallops/Mid-Atlantic Regional Spaceport. Wallops spokesman Jeremy Eggers confirms the picture is legitimate and was not altered in any way.
However, we cannot say with any certainty that no frog was harmed in the making of this picture.
Why would a frog be hanging around a launchpad? The launchpad at the Wallops/Mid-Atlantic Regional Spaceport has a “pool” for the high-volume water deluge system that activates during launches to protect the pad from damage and for noise suppression, and likely there was a (formerly) damp, cool place that was a nice spot for a frog to hang out.
Also, NASA has noted that like Kennedy Space Center, the Wallops Island Spaceport sits among a wildlife refuge. The 3,000 acre Wallops Island National Wildlife Refuge is comprised mainly of salt marsh and woodlands and is a habitat for a variety of species, including frogs. NASA writes:
“But how is it possible for wildlife to peacefully coexist with space operations and what effects do rocket launches have on wildlife? NASA’s launch facilities, roads, and facilities take up a small percentage of the area. The rest of the area remains undeveloped and provides excellent habitat for wildlife. During launches, short term disturbance occurs in the immediate vicinity of the launch pads, but the disturbance is short-lived allowing space launches and a wildlife habitat to coexist.”
This is not the first animal oddity to be included in a launch. There are several images of birds flying away from space shuttle launches, and in fact, during the STS-114 launch, a turkey vulture ran into the shuttle’s orange fuel tank (see video below). There was the famous space bat from the STS-119 shuttle launch in 2009, and recently the SpaceX Grasshopper test launch startled a herd of cows:

Update (9/12/13): NASA has now posted the picture on their Solar System Exploration website (I initially found it on imgur with no credit or source info).

Watch a year of incredibly detailed work in building the MAVEN spacecraft — sped up to take just 10 minutes. It’s the dance known as ATLO: Assembly, Test, and Launch Operations, set to a jazzy beat. The next spacecraft to Mars, the Mars Atmosphere and Volatile EvolutioN or MAVEN began ATLO procedures a year ago on Sept. 11, 2012. It was shipped to Kennedy Space Center’s Payload Hazardous Servicing Facility on Aug. 2, 2013 to begin preparations for its scheduled launch on Nov. 18, 2013.
Brian Koberlein is a professor at Rochester Institute of Technology. When he’s not teaching, though, he’s communicating science and education on Google+ of all places. Instead of doing a traditional blog, he’s posting article after article directly onto G+. He’s gathered a huge following on the social network, and a level of interaction that would make any blogger jealous.
Here’s an example of a post he did a couple of days ago on black hole thermodynamics.
And here’s one on detecting the atmospheres of extrasolar planets
Oh, Google+ now gives us the ability to embed posts onto our website, so I wanted to see what that looked like too. 🙂
For anyone who’s considering a field as a science journalist, I highly recommend you follow in Brian’s footsteps. Don’t wait for someone to give you permission to write and communicate science. Just get writing. People will notice, and with a large enough readership and body of work, you can get a job anywhere.
A major goal was to test the Comex-designed Gandolfi spacewalk training suit (based on the Russian Orlan spacesuits) during the sojourn. The mission was considered the first step (literally and figuratively) to figuring out how Europeans can train their astronauts for possible Moon, asteroid and Mars missions in the decades to come.
“The Gandolfi suit is bulky, has limited motion freedom, and requires some physical effort – just like actual space suits. I really felt like I was working and walking on the Moon,” Clervoy stated.
Even the photos come pretty darn close to the real thing. Compare this picture of Apollo 12 commander Pete Conrad during his Moon walk in 1969:

Water is considered a useful training tool for spacewalk simulations. NASA in fact has a ginormous pool called the Neutral Buoyancy Laboratory. Inside are duplicate International Space Station modules. Astronauts are fitted with weights and flotation devices to make them “float” similarly to how they would during spacewalks.
With trained divers hovering nearby, the astronauts practice the procedures they’ll need so that it’s second nature by the time they get into orbit. (NASA astronaut Mike Massimino once told Universe Today that one thing he wasn’t prepared for was how spectacular the view was during his spacewalk. Guess it beats the walls of a pool.)
The first tests for the Apollo 11 underwater simulations began at a pool run by Comex, a deep diving specialist in France, before the big show took place in the Mediterranean Sea off Marseille on Sept. 4. The crew members used tools similar to the Apollo 11 astronauts to pick up soil samples from the ground.

“Comex will make me relive the underwater operations of [Neil] Armstrong on the moon, but with an ESA-Comex scuba suit and European flag,” Clervoy wrote in French on Twitter on June 4, several weeks ahead of the mission.
And ESA promises there is more to come: “Further development for planetary surface simulations in Europe will be co-financed by the EU [European Union] as part of the Moonwalk project,” the agency wrote.
Clervoy isn’t the only European astronaut working in water these days. Starting Tuesday (Sept. 9), Andreas Mogensen and Thomas Pesquet joined an underwater lab as part of a five-person crew. Called Space Environment Analog for Testing EVA Systems and Training (SEATEST), it also includes NASA astronauts Joe Acaba and Kate Rubins, as well as Japanese Aerospace Exploration Agency (JAXA) astronaut Soichi Noguchi.

“The crew will spend five days in Florida International University’s Aquarius Reef Base undersea research habitat, conducting proof-of-concept engineering demonstrations and refining techniques in team communication. Additional test objectives will look at just-in-time training applications and spacewalking tool designs,” NASA stated on Sept. 6.
“We made it to Aquarius n [sic] did our first “spacewalk” today. From the ocean floor to space: Aquanaut to Astronaut. It is quite the adventure,” Acaba wrote on Twitter on Sept. 10. He walked twice in space on shuttle mission STS-119 in March 2009.
And a few days ago, ESA astronauts Alexander Gerst and Reid Wiseman, both bound for the station in 2014, were doing underwater training in the Neutral Buoyancy Laboratory. “Worked with @astro_reid in the pool today, and guess who we met?”, Gerst said on Twitter Sept. 5 while posting this picture below.
“Worked with @astro_reid [ESA astronaut Reid Wiseman] in the pool today, and guess who we met?” joked ESA astronaut Alexander Gerst on Twitter on Sept. 5, 2013.

The Expedition 36 crew from the International Space Station have landed safely, touching down in their Soyuz TMA-08M spacecraft in Kazakhstan at 02:38 UTC on September 11 (10:58 p.m. EDT Sept. 10). This great overhead image by NASA photographer Bill Ingalls shows the Soyuz’s thrusters firing just before it slams into the ground, ending up on its side. On board were Commander Pavel Vinogradov and Flight Engineer Alexander Misurkin of the Russian Federal Space Agency and NASA Flight Engineer Chris Cassidy. Vinigradov, age 60, is the oldest person to make the jarring landing in the venerable Soyuz craft.
You can see undocking and landing videos below:
The three completed 166 days in space since launching in late March. Remaining on the ISS are ESA astronaut Luca Parmitano, NASA astronaut Karen Nyberg and Russian cosmonaut Fyodor Yurchikhin, now comprising Expedition 37. They will be joined by the Oleg Kotov, Sergei Ryazansky and Michael Hopkins, set to launch on September 25.

New Comet Lovejoy starts out slow but quickly gains speed as it crosses from near Orion in mid-September to Ursa Major in November, when it will be closest to Earth. Created with Chris Marriott's SkyMap software
Move over Comet ISON. You’ve got company. Australian amateur astronomer Terry Lovejoy, discoverer of three previous comets, including the famous, long-tailed sungrazer C/2011 W3 (Lovejoy), just added a 4th to his tally.
This new comet will add to a lineup of comets that should grace early November skies in the northern hemisphere: Comets ISON, Encke and now the new Lovejoy.

The discovery of C/2013 R1 Lovejoy was announced on Sept. 9 after two nights of photographic observations by Lovejoy with an 8-inch (20 cm) Schmidt-Cassegrain reflector. When nabbed, the comet was a faint midge of about 14.5 magnitude crossing the border between Orion and Monoceros. Subsequent observations by other amateur astronomers peg it a bit brighter at 14.0 with a small, condensed coma.

Right now you’ll need a hefty telescope to catch a glimpse of Lovejoy’s latest, but come November the comet will glow at around 8th magnitude, making it a perfect target for smaller telescopes. At closest approach on the Nov. 23, Lovejoy will pass 38.1 million miles (61.3 million km) from Earth while sailing across the Big Dipper at a quick pace.
The comet is a faint 14th magnitude object just east of Orion’s Belt in the dim constellation Monoceros the Unicorn. The map shows its position tomorrow morning Sept. 11 just before the start of morning twilight. Stellarium
Mid to late November is also the time when Comet ISON, the current focus of much professional and amateur observation, will be at its brightest in the morning sky at around magnitude 2-3. Get ready for some busy nights at the telescope!

C/2013 R1 will whip by the sun on Christmas Day at a distance of 81 million miles (130.3 million km) and then return back to the deeps from whence it came.
The charts here give you a general idea of its location and path over the next couple months. As the comet crosses into small-scope territory in early November, I’ll provide maps for you to find it.

And as Stuart Atkinson noted on his website, Cumbrian Sky a great lineup should be in the northern hemisphere skies on November 9, 2013. From the left, Comet Encke will be magnitude 6, ISON should be at about magnitude 6 or 7; then Mars, followed by the new Comet Lovejoy, which will be still very faint at around magnitude 9, topped off by a bright Jupiter. The comets will not likely be of naked eye visibility, but this should be a great chance for astrophotographer to capture this lineup!
Comet Lovejoy is approaching the plane of the planets from “down under” (lower right). The diagram shows the comet’s position today. Like many comets, Lovejoy’s orbit is steeply inclined – in this case 62 degrees. Credit: NASA
Welcome to an exciting time for comet lovers, and congratulations Terry on another great discovery!
