The most distant Solar System object, Farout, has lost its crown after just two years. As Inverse reports, astronomers have confirmed that the planetoid Farfarout is now the farthest known Solar System object. It’s currently 132AU, or about 12.3 billion miles from the Sun (Farout is ‘just’ 120AU away), and its elongated orbit will take it 175AU away. For context, Pluto is 34AU from our host star — Farfarout reaches over five times that distance, and takes about 1,000 years to complete an orbit.

Astronomers Claim to Spot Multiple Bodies of Liquid Water on Mars
Two years ago, a team of Italian scientists claimed to have discovered a subglacial lake near the Martian south pole. The same team has collected further evidence to bolster this claim, including the apparent discovery of even more buried bodies of liquid water. The new research speaks to the potential for life on Mars, but not everyone is convinced by the evidence. Continue reading Astronomers Claim to Spot Multiple Bodies of Liquid Water on Mars
These two celestial bodies share a heartbeat, puzzling scientists
About 15,000 light-years away from Earth, a cloudy patch of space within our galaxy produces ultra-bright flashes of gamma radiation like clockwork. That’s not all—researchers found the unusual “heartbeat” coming from this cosmic gas cloud is beating along in time with the pulses of a black hole, located a whopping 100 light-years away from it. Researchers remain puzzled as to what the unusual long-distance relationship is between the two.

The Sun Produced Its Biggest Solar Flare Since 2017
Last month, the massive, hot ball of glowing hydrogen and helium at the center of our solar system—otherwise known as our sun—released its largest solar flare since October 2017. Although it’s too early to know for certain, NASA says in a statement that this new activity might indicate that the sun is “waking up” from its cyclical slumber. Continue reading The Sun Produced Its Biggest Solar Flare Since 2017
Extreme Dwarf Planet FarFarOut Could Be the Most Distant Known Object in the Solar System
Just months after discovering FarOut, the most distant known object in the Solar System, the same team of astronomers has detected the faint—but not yet confirmed—glimmerings of an object even farther away. Dubbed FarFarOut, the extreme dwarf planet is 13 billion miles away—a distance so far it takes nearly 20 hours for the Sun’s rays to reach it.

Saturn’s Rings Rain Organic Compounds Into Its Atmosphere
The Cassini space probe’s fatal plummet into Saturn has revealed that the gas giant’s innermost ring sheds icy showers of rain and organic molecules into the planet’s upper atmosphere at an incredible rate.

Jupiter’s magnetic field has two ‘south poles’
Jupiter’s magnetic field is profoundly different from that of all other known planets — it essentially has two magnetic south poles instead of just one, a new Nature studyfinds. Continue reading Jupiter’s magnetic field has two ‘south poles’
