A newly found young star cluster on the outskirts of our Milky Way seems to be made of material from the Magellanic Clouds. It appears the collision between the Clouds and our Milky Way may already be starting.

When the 2 stars in the binary star system V Sagittae come together - around the year 2083, astronomers say - they'll create a star explosion called a nova. Then V Sagittae will temporarily outshine all the stars in our Milky Way galaxy.

The SOFIA flying telescope has captured a new panoramic image of the center of our home galaxy, the Milky Way. The image shows a region more than 600 light-years across, revealing unprecedented details within the center's dense swirls of gas and dust.

New observations of "super-puff" exoplanets by the Hubble Space Telescope have provided scientists with more clues about these enigmatic and strange worlds.

The red supergiant star Betelgeuse, a bright star in the constellation of Orion, has been making headlines due to a recent drop in brightness. Is an explosion imminent? If it happens, will Earth be affected?

We've known for some time that Venus has vast lava plains, fields of small lava domes, and large shield volcanoes. But does it still have active volcanoes? A new study involving lava flows on Venus suggests that, yes, it does.

New observations reveal that - about a billion years ago - the center of our Milky Way galaxy underwent a period of intense star formation, resulting in over 100,000 supernovae.

From the 1st landing on the moon's far side to the 1st actual image of a black hole, here’s a quick roundup of 9 of the stories our readers enjoyed most in 2019.

The well-known bright star Betelgeuse - a red giant star, famous for its name and for the fact that it'll explode someday - has become noticeably dimmer since late October. Here's what astronomers think is happening.

Thirty-two years ago, Supernova 1987A erupted in the nearby Large Magellanic Cloud. Astronomers using the ALMA radio telescope now say they've found the small, compact neutron star created in this mighty star explosion.
