Direct link Planet-eating star could be lurking in nearby cluster

13 Sep 2019, 14:39 UTC An unusual set of chemical fingerprints spotted in the light from a distant star could be the remnants of a digested planet, according to a new study by researchers in Sweden. In 2017 astronomers making spectroscopic observations of several stars in the open star cluster Messier 67 spotted one – dubbed Y2235 – with elevated levels of certain elements on its “surface”. These included carbon, magnesium and oxygen as well as heavier elements such as cerium, iron and yttrium.

Direct link This Ridiculously Speedy Star Might Be Running Away from a Rare, Unproven Type of Black Hole

13 Sep 2019, 12:03 UTC Astronomers have discovered a bright, young star that is running away from home. Why? What did the star's parents do to deserve this? According to a study published Aug. 6 in the journal Astronomy & Astrophysics, it's nobody's fault; it seems the young star simply fell in with the wrong crowd — namely, a very hungry black hole.

13 Sep 2019, 11:15 UTC If you could pack a hot air balloon onto an interstellar spaceship and travel 110 light years to a certain planet orbiting a dim star in the constellation Leo, you’d have an experience not entirely unlike ballooning on Earth. The temperature, pressure, and moist air could feel quite pleasant, though you’d need an oxygen mask—and possibly an umbrella.

13 Sep 2019, 07:33 UTC Hubble has captured a new image of Saturn that makes you wonder if it’s even real. The image is so crisp it makes it look like Saturn is just floating in space. Which it is. This image of the ringed-planet was captured when Saturn was at its closest to Earth, some 1.36 billion km away (845 million miles) on June 20th, 2019. The crisp image was captured with Hubble’s Wide Field Camera 3 (WFC3.)

Direct link Astronomers Find a Supermassive Black Hole That’s Feasting on a Regular Schedule, Every 9 Hours

13 Sep 2019, 07:22 UTC Astronomers have found a supermassive black hole (SMBH) with an unusually regular feeding schedule. The behemoth is an active galactic nucleus (AGN) at the heart of the Seyfert 2 galaxy GSN 069. The AGN is about 250 million light years from Earth, and contains about 400,000 times the mass of the Sun.

Direct link Galaxy collisions and star-formation: a surprising causal examination

12 Sep 2019, 13:00 UTC The fundamental constituents of galaxies are stars, gas, dust, black holes, and dark matter. The extent to which we understand each of them and their interplay varies greatly. Yet current understanding drives us to acknowledge that the growth of the mass of galaxies must be driven by either active star-formation, galaxy-galaxy mergers, or both. But which of these two effects dominates is an ongoing mystery nearly as old as the discovery of galaxies themselves.
