While Saturn’s rings may disappear in less than 100 million years because gravity is pulling them into the planet, apparently they haven’t always surrounded the planet, either. The finding was published in the journal Science on Thursday.

A series of new animations by a NASA scientist show just how zippy — and also how torturously slow — the speed of light can be.

NASA’s newest planet-hunting probe has bagged another alien world, the eighth confirmed find for the young mission.
The Transiting Exoplanet Survey Satellite (TESS) has discovered a planet orbiting the star HD 21749, which lies about 53 light-years from Earth in the faint constellation Reticulum, scientists announced today (Jan. 7).

NASA’s New Horizons is en route to Ultima Thule, a journey that will see the NASA spacecraft whiz past this mysterious Kuiper Belt object on New Year’s Day. But as the probe nears, mission specialists are already having to deal with a rather strange observation—an anomaly in the way Ultima Thule is reflecting incoming light.

The search for extraterrestrial life will continue not just on the surfaces of planets, but deep within their icy cores.
For decades, rovers and landers on planets such as Mars have either examined or roamed the surface to find evidence for flourishing microbial life, or at least the ancient remnants of it. However, this could be all about to change with the development of a new robot that can burrow deep within a planet’s surface.

New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 & 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.

The Parker Solar Probe is doing well after its first flyby of the sun, and it will soon begin returning groundbreaking data about how our star behaves.
Yesterday (Dec. 12), four researchers gathered at this year’s fall meeting of the American Geophysical Union (AGU) in Washington, D.C., to share the early success of NASA’s Parker Solar Probe.

When we think of our first contact with alien life, many people imagine a small green humanoid in a flying saucer. The reality will be much different. NASA’s Chief Scientist, Ellen Stofan, explains what we should expect when we do discover extraterrestrial life.

The universe is so unfathomably huge that our tiny human brains can barely imagine just how big it really is out there. Case in point, a paper recently published in the Astrophysics Journal estimates that the mass of the Milky Way galaxy is 9.5 x 10^41 kilograms — 4.8 x 10^11 times the mass of the sun. That sounds wild, but can those impossibly gigantic numbers mean anything to us? Continue reading The Milky Way is 392 decillion times more massive than the heaviest thing we’ve ever weighed
