Water found in habitable super-Earth's atmosphere for first time

Astronomers have finally uncovered water vapor in the atmosphere of a super-Earth exoplanet orbiting within the habitable zone of its star. The find means that liquid water could also exist on the rocky world's surface, potentially even forming a global ocean. The discovery, made with NASA's Hubble Space Telescope, serves as the first detection of water vapor in the atmosphere...

Giant bubbles spotted rushing out from Milky Way’s center

The Milky Way is blowing bubbles. Two giant radio bubbles, extending out from the galaxy for over 1,400 light years, were just discovered in X-ray data. Astronomers think the bubbles started forming a few million years ago due to some type of cataclysmic event near the galaxy’s central supermassive black hole. The bubbles’ location also closely matches the range of over 10...

Mysterious dark patches in Venus’ clouds are affecting the weather there

Something mysterious swirls amidst the clouds of Venus.The planet’s hot, harsh atmosphere is thick with carbon dioxide and sulfuric acid. Atmospheric gases circulate amid cloud layers according to patterns that scientists don’t fully understand. And Venusian clouds also contain strange, dark patches, called “unknown absorbers” because they absorb large amounts of solar radi...

Shredded exomoon may explain weird behavior of Tabby’s Star

An artist’s concept of a ring of dust orbiting Tabby’s Star. NASA/JPL-Caltech About four years ago, one star gained notoriety when some astronomers suggested its weird light pattern could be...

Astronomers can't agree on galaxies without dark matter

The discovery of two ghostly galaxies devoid of dark matter created quite a stir in the astronomical community. But the jury's still out on what's really going on. NGC1052-DF2 is a large, but very diffuse galaxy located some 65 million light-years away. This image of the galaxy, which is thought to contain a negligible amount of dark matter, was captured by the Advanced Ca...

Cosmic collision may reveal how giant stars form

Astronomers have witnessed a rare event: the birth of massive stars 2.73 million light-years away in the Triangulum Galaxy (Messier 33). At the center of two giant colliding gas clouds are some 10 young stars with masses tens of times that of the Sun. Their discovery indicates that such cloud-cloud collisions are a main pathway to creating giant stars in the nearby universe, which could...
