SpaceX Starship Hopper Prototype Makes its Highest Hop Test So Far!

Yesterday (Tuesday, Aug. 26th), SpaceX conducted the second untethered test of its Starship Hopper – and nailed it! For this test, the prototype test vehicle took off from the Boca Chica test facility, ascended to an altitude of 150 m (~500 ft) and then landed again safely. This comes just a month after the first successful hop test and brings the company one step closer to tests using their full-scale prototype.

Screaming Sounds Sent to the Edge of Space, Confirming That… “In Space, No One Can Hear You Scream”

A unique, low-cost, and crowd-scream-sourced experiment has proven what all sci-fi movie fans know is true: In space, no one can hear you scream.”

That line is the tag line from the famous 1979 movie Alien, of course. And now an innovative experiment in Britain has shown that the writer of that movie was correct. To prove it, they used off-the-shelf electronics, an inexpensive balloon, and the recorded screams from a mother in South Africa.

There Should Be More Iron In Space. Why Can’t We See It?

For the first time, NASA's Spitzer Space Telescope has detected little spheres of carbon, called buckyballs, in a galaxy beyond our Milky Way galaxy. The space balls were detected in a dying star, called a planetary nebula, within the nearby galaxy, the Small Magellanic Cloud. What's more, huge quantities were found -- the equivalent in mass to 15 of our moons. An infrared photo of the Small Magellanic Cloud taken by Spitzer is shown here in this artist's illustration, with two callouts. The middle callout shows a magnified view of an example of a planetary nebula, and the right callout shows an even further magnified depiction of buckyballs, which consist of 60 carbon atoms arranged like soccer balls. In July 2010, astronomers reported using Spitzer to find the first confirmed proof of buckyballs. Since then, Spitzer has detected the molecules again in our own galaxy -- as well as in the Small Magellanic Cloud. Image Credit: NASA/JPL-Caltech

Iron is one of the most abundant elements in the Universe, along with lighter elements like hydrogen, oxygen, and carbon. Out in interstellar space, there should be abundant quantities of iron in its gaseous form. So why, when astrophysicist look out into space, do they see so little of it?

LightSail 2 Mission is Going Strong and Sending Mission Info Home!

On June 25th, 2019, The Planetary Society‘s cubesat spacecraft known as LightSail 2 lifted off from the NASA Kennedy Space Center in Florida aboard a Falcon Heavy rocket. This was the second solar sail launched the Society, the first (LightSail 1) having been sent into space in 2015. Like its predecessor, the purpose of this spacecraft is to demonstrate the technology that would allow for solar sails operating within Low Earth Orbit (LEO).

Since reaching orbit, the LightSail 2 has been indicated that it is in good working order, as indicated by the Mission Control Dashboard recently introduced by The Planetary Society. In addition to establishing two-way communications with mission controllers and passing a battery of checkouts, the spacecraft also took its first pictures of Earth (and some selfies for good measure).

French Scientists Claim to Have Created Metallic Hydrogen

Scientists have long speculated that at the heart of a gas giant, the laws of material physics undergo some radical changes. In these kinds of extreme pressure environments, hydrogen gas is compressed to the point that it actually becomes a metal. For years, scientists have been looking for a way to create metallic hydrogen synthetically because of the endless applications it would offer.

At present, the only known way to do this is to compress hydrogen atoms using a diamond anvil until they change their state. And after decades of attempts (and 80 years since it was first theorized), a team of French scientists may have finally created metallic hydrogen in a laboratory setting. While there is plenty of skepticism, there are many in scientific community who believe this latest claim could be true.

In what Elon Musk is calling their “most difficult” mission so far, SpaceX launched the Falcon Heavy rocket for the third time. The launch took place at 2:30 am ET Tuesday from a launch pad at Kennedy Space Center in Florida. The mission was called STP-2, and Universe Today sent a photographer to capture all the action.

Competition Will Let You Name an Exoplanet

Within the framework of its 100th anniversary commemorations, the International Astronomical Union (IAU) is organising the IAU100 NameExoWorlds global competition that allows any country in the world to give a popular name to a selected exoplanet and its host star. Image Credit: IAU/L. Calçada

When it comes to naming all those exoplanets that astronomers keep finding, it’s up to the International Astronomical Union (IAU) to do the job. In an effort to reach out to the global community, they’re running a new contest. In honour of their 100 year anniversary, the IAU has organized the 100IAU NameExoWorlds event.

Don’t Worry About Asteroid 2006QV89. There’s Only a 1 in 7000 Chance It’ll Hit the Earth in September

Whenever scientists announce an upcoming close encounter with an asteroid, certain corners of the internet light up like the synaptic rush that accompanies a meth binge, with panicky headlines shouted straight from the brain stem. But never mind that. We’re not that corner of the internet. We’re sober, yo!

The ESA is developing its own spacecraft capable of re-entry into Earth’s atmosphere. The reusable spacecraft is called the Space RIDER (Reusable Integrated Demonstrator for Europe Return), and the ESA says that the Space Rider will be ready for launch by 2022. It’s being designed to launch on the Vega-C rocket from Europe’s spaceport in Kourou, French Guiana.

Here’s Where Beresheet Crashed into the Moon

The Beresheet lander came oh-so-close to touching down on the surface of the Moon, but something went wrong and it didn’t make it. Now, thanks to the Lunar Reconnaissance Orbiter, the exact point of impact can be seen.
