There’s Another Ocean Moon Candidate: Uranus’ Tiny Moon Miranda

29-10-2024 23:28 via universetoday.com

The Solar System’s hundreds of moons are like puzzle pieces. Together, they make a picture of all the forces that can create and modify them and the forces that shape our Solar System. One of them is Miranda, one of 28 known moons that orbit the ice giant Uranus. Miranda is its smallest major moon, at 471 km in diameter.
New research shows that this relatively small, distant moon may be hiding something: a subsurface ocean.Miranda stands out from the other moons for one reason: its surface

Titan May Have a Methane Crust 10 Km Thick

29-10-2024 19:58 via universetoday.com

Saturn’s moon, Titan, is an anomaly among moons. No other moons have surface liquids, and aside from Earth, it’s the only other Solar System object with liquids on its surface. However, since Titan is so cold, the liquids are hydrocarbons, not water. Titan’s water is all frozen into a surface layer of ice.New research suggests that under the surface, Titan is hiding another anomaly: a thick crust of methane.
The evidence for the methane comes mostly from craters. Observations h

Death of a Comet: S1 Didn’t Survive its Sungrazing Plummet

Sungrazer C/2024 S1 ATLAS broke apart at perihelion.Alas, a ‘Great Halloween Comet’ was not to be. The Universe teased us just a bit this month, with the potential promise of a second naked eye comet in October: C/2024 S1 ATLAS. Discovered on the night of September 27th by the Asteroid Terrestrial Last-alert impact System (ATLAS) all-sky survey, this inbound comet was surprisingly bright and active for its relative distance from the Sun at the time of discovery. This gave the comet t

Chandra neemt superluminale snelheden waar in de jet van Centaurus A

29-10-2024 11:26 via astroblogs.nl

Centaurus A (NGC 5128) is een lensvormig sterrenstelsel in het sterrenbeeld Centaurus op 12 miljoen lichtjaar afstand, da’s voor sterrenkundigen bij wijze van om de hoek. Centaurus A is een sterke bron van radiogolven en in het centrum ervan bevindt zich een superzwaar zwart gat. Vanuit dat centrum schiet een jet of straalstroom vol met […]

Saturnusmaan Titan heeft kilometers dikke isolerende methaanrijke korst

29-10-2024 07:46 via spacepage.be

De grootste maan van Saturnus, Titan, is de enige plek buiten de aarde waarvan bekend is dat hij een atmosfeer heeft en vloeistoffen in de vorm van rivieren, meren en zeeën op zijn oppervlak. Vanwege de extreem koude temperatuur bestaan de vloeistoffen op Titan uit koolwaterstoffen zoals methaan en ethaan en bestaat het oppervlak uit vast waterijs.

Remember that “Alien Signal” Sent by the ExoMars Orbiter Last Year? It’s Just Been Decoded

29-10-2024 01:05 via universetoday.com

In May 2023, the ESA’s Exomars Trace Gas Orbiter (TGO), currently in orbit around Mars, sent a signal to Earth to simulate a possible extraterrestrial transmission. As part of the multidisciplinary art project “A Sign in Space,” the purpose was to engage citizen scientists in helping to decode it. The campaign was inspired by Cosmicomics by Italian writer/journalist Italo Calvino, a series of short stories exploring various scientific principles. The project is partnered with t
