Mars may be known as the red planet, but a European spacecraft found oxygen that is causing a green glow in the planet's atmosphere, according to a new study.
On Earth, this occurs in the form of auroras at the planet's poles, but this is the first time this kind of glow has been seen around another planet.
Earth's polar green glow happens when electrons from space collide with our upper atmosphere, but the atmospheres of Earth and Mars both glow during the day and at night thanks to sunlight. At night, a glow is created when molecules in the atmosphere that broke apart come back together. During the day, the glow occurs when sunlight agitates atmospheric molecules and atoms, like nitrogen and oxygen.

We'll Clean-Up Space Junk Using Sticky Foam 'Spiderwebs' In Orbit, Says Russian Space Startup
StartRocket wants to create sticky "spiderweb" satellites that can spray space junk with polymeric ... [+] foam that will then sink safely burn-up in the atmosphere.
After more than half a century of space activity there are about half a million man-made "things" orbiting our planet. Trash, debris, junk. These big and tiny objects—from defunct satellites to flecks of paint—take-up valuable orbits that satellites could be in, and they're a collision risk for satellites and spacecraft.

There Could Be Up to 6 Billion Earth-Like Planets Out There in The Milky Way
Now, with years of exoplanet-hunting data in the bag, astronomers have made a new calculation and determined there could be as many as 6 billion Earth-like planets orbiting Sun-like stars in the Milky Way.
"My calculations place an upper limit of 0.18 Earth-like planets per G-type star," said astronomer Michelle Kunimoto from the University of British Columbia (UBC) in Canada. (You may remember that Kunimoto discovered a whopping 17 exoplanets in Kepler data quite recently.)

Virgin Orbit's first air-launched rocket launch fails - Universe Today
The reason people use the aphorism "it isn't rocket science" is because rocket science is hard. Virgin Orbit , a spin-off of Virgin Galactic that focuses on small satellite launches, proved that with a recent test of its LauncherOne rocket.
The LauncherOne, which has been in development for more than 7 years, was designed to serve as a plane-based orbital delivery system. It is dropped from a 747 (the current iteration is nicknamed "Cosmic Girl"), which gives it some advantages over competing small satellite launch technologies, such as flexible launch schedules and the ability to reach almost any orbital inclination.
