In an unexpected discovery, astronomers have surprised a supermassive black hole that had been dormant for the past decades “waking up” and feasting upon an unsuspecting planet that had drifted too close to its event horizon.  The mass of the planet hints towards a giant Jupiter or a small brown dwarf. Also, a similar event [...]

To boldly go where no man has gone before: a spacecraft launched from Earth, Voyager I has pushed into the great unknown, leaving behind our solar system. For years, astronomers have been discussing about when Voyager will finally leave the solar system – and it’s actually pretty hard to draw a line and say that [...]

Despite all the magnificent advancements in the field, we are still in the infancy of our research on extraterrestrial planets, so it shouldn’t really surprise anybody if a new type of planet is found. Mysterious dense bodies outside the Solar System which have puzzled astronomers for quite a while may in fact be remnants of [...]

A new analysis of data from NASA’s Lunar Orbiter Laser Altimeter (LOLA) shows that molten rock created by lunar impacts has been around for much longer than previously believed. During its earliest days, the Moon was covered in an ocean of molten rock, pretty much like every planet out there. As that lunar magma ocean [...]

A pair of newly discovered stars is the third-closest star system to the Sun – the closest astronomers have found a star system since 1916. The discovery was made by Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State University. Both stars in the system are brown dwarfs – not exactly stars, [...]

Researchers have for the first time conducted a remote reconnaissance of a distant planetary system with a new telescope imaging system. Peeking at other planets Project 1640 is a dedicated high contrast imaging program at Palomar Observatory with the goal of obtaining images and spectra of brown dwarfs and planetary mass companions to nearby stars. [...]

Researchers have, for the first time, calculated the distance to the Large Magellanic Cloud, a galaxy neighboring the Milky Way. Care to take a guess? According to these calculations, it’s just 163.000 light-years away. For measurements inside our solar system, researchers use a technique called parallax. Parallax is a displacement or difference in the apparent [...]

Astronomers using ESO’s Very Large Telescope have obtained what is likely the first direct observation of a forming planet still embedded in a thick disc of gas and dust. If the finding is confirmed, it could significantly boost what we already know about forming planets. An international team led by Sascha Quanz (ETH Zurich, Switzerland) [...]

A ring of radiation that scientists knew nothing about fleetingly surrounded our planet last year, before being blown away by a powerful interplanetary shock, researchers say. Astronomic intuition Usually, whenever NASA launches a spacecraft, they wait weeks or even months to finely tune all its instruments. It’s a rite of passage that all shuttles (and [...]

A metal poor star located in the Milky Way galaxy, “just” 190 light years away from our Sun is 14.46+-0.80 billion years old – nearly as much as the age of the Universe! All stars follow a stellar evolutionary path; by knowing some parameters about the star (such as mass, luminosity, and surface temperature), astronomers [...]
