Astronomers Find a Planet With Three Times the Mass of Jupiter Jupiter is the Boss. 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: Most of the orbits of the Solar System’s planets are closer to Jupiter’s orbital plane … Continue reading “Astronomers Find a Planet With Three Times the Mass of Jupiter” The post Astronomers Find a Planet With Three Times the Mass of Jupiter appeared first on Universe Today.

Worlds With Hydrogen in Their Atmospheres Could Be the Perfect Place to Search for Life We’re waiting patiently for telescopes like the James Webb Space Telescope to see first light, and one of the reasons is its ability to study the atmospheres of exoplanets. The idea is to look for biosignatures: things like oxygen and methane. But a new study says that exoplanets with hydrogen in their atmospheres are a … Continue reading “Worlds With Hydrogen in Their Atmospheres Could Be the Perfect Place to Search for Life” The post Worlds With Hydrogen in Their Atmospheres Could Be the Perfect Place to Search for LifeRead More →

Rocky Planets Orbiting White Dwarf Stars Could be the Perfect Places to Search for Life Some very powerful telescopes will see first light in the near future. One of them is the long-awaited James Webb Space Telescope (JWST.) One of JWST’s roles—and the role of the other upcoming ‘scopes as well—is to look for biosignatures in the atmospheres of exoplanets. Now a new study is showing that finding those biosignatures … Continue reading “Rocky Planets Orbiting White Dwarf Stars Could be the Perfect Places to Search for Life” The post Rocky Planets Orbiting White Dwarf Stars Could be the Perfect Places to Search for LifeRead More →

NASA’s Perseverance Rover is Going to Jezero Crater, Which is Looking Better and Better as a Place to Search for Evidence of Past Life on Mars In 2018, NASA decided that the landing site for its Mars 2020 Perseverance rover would be the Jezero Crater. At the time, NASA said the Jezero Crater was one of the “oldest and most scientifically interesting landscapes Mars has to offer.” That assessment hasn’t changed; in fact it’s gotten stronger. A new research paper says … Continue reading “NASA’s Perseverance Rover is Going to Jezero Crater, Which is Looking Better and Better as a Place to Search for EvidenceRead More →

Terrible Luck. The Only Person Ever Killed by a Meteorite – Back in 1888 What are your chances of getting smacked – and killed — by a meteorite? One astronomer put the odds of death by space rock at 1 in 700,000 in a lifetime, while others say it’s more like 1 in 1,600,000. Computing the probability for such an untimely death is difficult because this type of event … Continue reading “Terrible Luck.

There Might Be Dust Devils On Titan Too Saturn’s moon Titan is alone among the Solar System’s moons. It’s the only one with any atmosphere to speak of. Other moons may have thin, largely insignificant atmospheres, like Ganymede with its potential oxygen atmosphere. But Titan’s atmosphere is dense, and rich in nitrogen. A new study shows that Titan’s atmosphere and winds might produce … Continue reading “There Might Be Dust Devils On Titan Too” The post There Might Be Dust Devils On Titan Too appeared first on Universe Today.
