Are these 19 eccentric asteroids from other star systems?

In the first discovery of its kind, researchers in France have found 19 asteroids in our solar system - between the planets Jupiter and Neptune - that they say are likely of interstellar origin.

Are giant magnetic bubbles depleting Uranus’ atmosphere?

Researchers at NASA’s Goddard Space Flight Center, looking at old data from Voyager 2, have found evidence that plasmoids are slowly causing Uranus' atmosphere to leak into space.

A unique (so far) gravitational wave signal

LIGO and Virgo detectors have now captured the first gravitational waves from a binary black hole merger where the black hole masses are unequal.

Hubble celebrates its 30th anniversary

The Hubble Space Telescope was launched on April 24, 1990. It's spent the past 3 decades acquiring magnificent images of distant space objects, providing a time machine that's taken astronomers back to when the universe was less than a billion years old.

A beloved exoplanet turns to dust

Fomalhaut b was thought to be one of the few exoplanets photographed so far, but new observations from the Hubble Space Telescope show it's really an expanding dust cloud.

Update on 2I/Borisov, the first known interstellar comet

The first known interstellar comet - 21/Borisov - probably came here from a red dwarf star, according to a new study of data from the Hubble Space Telescope.

Two (potentially) exciting new exoplanet discoveries

Scientists just announced 2 new exciting updates about exoplanets. One is a potentially habitable world similar in size and temperature to Earth. The other is a possible new planet - possibly with rings - orbiting the closest star to our sun, Proxima Centauri.

How WFIRST will use warped spacetime to find exoplanets

NASA's WFIRST mission - an infrared space observatory planned for launch around 2025 - will use the fact that the gravity of distant objects warps spacetime, bending and focusing light, thereby revealing new worlds.
