New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 and 2 observations made decades ago. The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn's magnetic field.
A team of astronomers has discovered the most-distant body ever observed in our solar system. It is the first known solar system object that has been detected at a distance that is more than 100 times farther than Earth is from the sun. It was announced Monday by the International Astronomical Union's Minor Planet Center. Carnegie's Scott S. Sheppard, the University of Hawaii's David Tholen, and Northern Arizona University's Chad Trujillo made the discovery.
Lab simulations nix the common wisdom that atmospheric oxygen and organic compounds are good evidence that a planet harbors life.
In the search for life on other planets, scientists traditionally have looked for a world with water. But an Ohio State geophysicist wonders if we should look to rocks instead.
Now, astronomers have used Hubble to nab a second 'very warm' Neptune (GJ 3470b) that is losing its atmosphere at a rate 100 times faster than that of GJ 436b. Both planets reside about 3.7 million miles from their star. That's one-tenth the distance between our solar system's innermost planet, Mercury, and the Sun.
In their quest to learn more about faraway planets, astronomers discovered that a medium-sized planet roughly the size of Neptune is evaporating at a rate 100 times faster than a previously discovered planet of similar size.
'Where did the hot Neptunes go?' This is the question astronomers have been asking for a long time, faced with the mysterious absence of planets the size of Neptune. A team of researchers led by UNIGE has just discovered that one of these planets is losing its atmosphere at a frantic pace. This observation strengthens the theory that hot Neptunes have lost much of their atmosphere and turned into smaller planets called super-Earths.
UNLV researchers Shangjia Zhang and Zhaohuan Zhu led a team of international astronomers in a study that used the powerful ALMA telescope to discover that in other parts of the Milky Way Galaxy (seen here) there is potentially a large population of young planets -- similar in mass to Neptune or Jupiter -- at wide-orbit that are not detectable by other current planet searching techniques.
A team of astronomers has conducted ALMA's first large-scale, high-resolution survey of protoplanetary disks, the belts of dust and gas around young stars.
Spectral observations made by the OSIRIS-REx spacecraft identified hydrated minerals across the asteroid, confirming that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study the composition of primitive volatiles and organics.
