Space Titan is Saturn’s largest moon. It has a dense, hazy atmosphere made mostly of nitrogen. Titan’s atmosphere is wobbling like a gyroscope, a new study of data from the Cassini mission has found. Why is it doing that? Some unknown event in Titan’s past likely knocked the atmosphere off-kilter, the researchers said. Saturn’s largest moon Titan has a dense atmosphere composed mostly of nitrogen. You might expect that it rotates around in sync with the moon’s surface, but it doesn’t.

Space The TRAPPIST-1 planetary system has seven known rocky planets. All of them are close to Earth’s size. Could any of them have water, and be potentially habitable? A new study says yes, although the amount of water might vary greatly among the planets. Volcanic outgassing is possible on the planets, but that might vary from planet to planet. Some of the planets might have greater volcanic activity than Earth, while others have less.

Space Looking up has never felt more important. Please donate to help EarthSky keep bringing the sky to your screen. Long, dark streaks on steep slopes on Mars have puzzled scientists for decades. Some only last for days while others can remain for years. Could they be signs of liquid water? Brief flows of briny (salty) water could explain the streaks, some scientists said. But a new study of over 500,000 streaks disputes that.

Space EarthSky’s Will Triggs talks about the odd sphere in space. Video via EarthSky. Science matters. Wonder matters. You matter. Join our 2025 Donation Campaign today. Spherical objects are common in space. They can include stars, planets and some moons. What else might there be? An international team of astronomers has found a new spherical oddity in our Milky Way galaxy. It looks like a giant bubble and is nearly perfectly circular.

Space Science matters. Wonder matters. You matter. Join our 2025 Donation Campaign today. HD 89389 is a sunlike star about 100 light-years from Earth. It is slightly brighter and more massive than our sun. A recent optical SETI search found a pair of very fast, identical pulses coming from the star. Optical SETI looks for light signals such as laser instead of radio signals. What caused them? An object passing in front of the star is the most likely explanation.

RT @Angry_Staffer: It’s really depressing how absolutely shit Twitter is for breaking news now. India and Pakistan are actively attacking…
AARO just released an unresolved #UAP report from the Middle East in 2023, with infrared video. All the sensor information is missing from the video though. 🤔 https://t.co/RQS2sKQvKe
Eight minutes and fifteen seconds of video footage was captured by an infrared sensor aboard a U.S. platform in the Middle East in 2023 and later reported to AARO as UAP. The report remains unresolved as the available data does not support a conclusive analytic evaluation.
