In a paper published today in the journal Nature Astronomy , she and her colleagues have observed in laboratory studies that microbes can survive and thrive in atmospheres that are dominated by hydrogen — an environment that is vastly different from Earth’s nitrogen- and oxygen-rich atmosphere.
Hydrogen is a much lighter gas than either nitrogen or oxygen, and an atmosphere rich with hydrogen would extend much farther out from a rocky planet. It could therefore be more easily spotted and studied by powerful telescopes, compared to planets with more compact, Earth-like atmospheres.

Astronomers Find a Planet With Three Times the Mass of Jupiter - Universe Today
Well, in terms of planets in our Solar System it is. It’s played a huge role in shaping the Solar System due to its mass and its gravity. Here’s a few ways it’s shaped our system:
That’s just a sample of the effects that massive Jupiter has on the Solar System. It’s all due to Jupiter’s mass, which is about 2.5 times greater than all the other planets.
Now astronomers have found an exoplanet that’s three times more massive than Jupiter. How has that planet shaped its own Solar System?
Was Mars once 'blue'?
NASA has released a photo taken by its Curiosity rover that shows a mysterious, unexplained white light on Mars.
Scientists have discovered 4-billion-year-old organic molecules containing nitrogen in a Martian meteorite, shedding new light on the red planet’s early history.
The meteorite, ALH 84001, was ejected from the surface of the red planet 15 million years ago, according to scientists. It was found in Antarctica in 1984.

Change is coming to our evening sky. The bright planet Venus now captivating viewers is going to drop out of view in the next month.
Venus is high in the western sky after sunset, as high as it will get in the evening sky. Pay attention and you'll notice each night ahead. It will appear lower. By the end of May it will have dropped from view.
If you are up late at night you'll see two of the solar system's largest planets, Jupiter and Saturn, appear together low in the eastern sky. Jupiter is the brighter of the two.
Newly discovered exoplanet dethrones former king of Kepler-88 planetary system
A team of astronomers led by the University of Hawaii Institute for Astronomy (UH IfA) has discovered a planet three times the mass of Jupiter in a distant planetary system.
The discovery is based on six years of data taken at W. M. Keck Observatory on Maunakea in Hawaii. Using the High-Resolution Echelle Spectrometer (HIRES) instrument on the 10-meter Keck I telescope, the team confirmed that the planet, named Kepler-88 d, orbits its star every four years, and its orbit is not circular, but elliptical. At three times the mass of Jupiter, Kepler-88 d is the most massive planet in this system.
Scientists optimistic planetary probes won’t face coronavirus launch delays –
Launches of interplanetary missions can only depart Earth when the positions of the planets are just right, and officials managing the development of probes set for launch in 2021 and 2022 to explore asteroids and Jupiter says construction milestones and reviews are proceeding to keep the projects on schedule despite the coronavirus pandemic.
NASA’s next planetary mission, the Perseverance Mars rover, remains on schedule for liftoff July 17 from Cape Canaveral. NASA has assigned a high priority to the Perseverance rover, and agency is using government aircraft to shuttle workers between the Kennedy Space Center and the rover team’s home base at the Jet Propulsion Laboratory in Pasadena, California.
How Much Energy Does It Take to Blow Up a Planet? | WIRED
I know what you're thinking: How much energy would it take to blow up a planet? Of course, it's just an academic question. I'm sure you're not a Sith lord with bad intentions, so I'll show you how to figure this out. But even if this is not a real thing, it's still fun to calculate.
This position is measured in pixels, but we can convert it to distance by scaling it to a known object in the scene. Then we can get time data from the frame rate—24 frames per second in this case. Assuming the scene is filmed at regular speed (i.e., not slow motion), we know that each frame represents 1/24th of a second. With position and time data, we can the compute the speed.
