ESO images “dog bone” asteroid called Kleopatra in detail

At the European Southern Observatory, Astronomers have leveraged the Very Large Telescope to take the most detailed images of a peculiar asteroid known as Kleopatra. The asteroid is shaped like a dog bone and is quite large at 270 kilometers. To put its size in perspective, 270 kilometers is roughly half the length of the English Channel.

In this glowing exoplanet forge, a moon’s birth caught for the first time

The birth of a distant, alien moon has been spotted by astronomers, the first time what's still a little-understood phenomenon has been observed. Although moons - like our own - are not rare, actual opportunities to watch as they, and planets, form have proved elusive.

ESO astronomers share galaxy images that look like fireworks

A team of astronomers from the European Southern Observatory (ESO) have released some new observations of galaxies that look like colorful explosions of fireworks in the sky. The images were obtained using the ESL Very Large Telescope (VLT) and show different components of each galaxy in distinct colors. The multiple colors allow astronomers to pinpoint the locations of young stars and the warm gas they produce around them.

ESO telescopes record the final moments of a star being consumed by a black hole

ESO telescopes record the final moments of a star being consumed by a black hole

Telescopes at the European Southern Observatory and other organizations worldwide have spied a rare blast of light originating from a star as it was being ripped apart by a supermassive black hole. The phenomenon is known as a tidal disruption event, and the event was the closest flare ever recorded at 215 million light-years from Earth.

ESO VLT observes signs of a planet being born around a distant star

ESO VLT observes signs of a planet being born around a distant star

Astronomers have observed what appears to be a planet being born using the European Southern Observatory's Very Large Telescope or VLT. The signs of planet formation were observed around a young star called AB Aurigae that has a dense disc of dust and gas around it. Inside that disc, the astronomers spotted a prominent spiral structure with a twist that marks the site where the planet could be forming.

ESO observations have revealed a star orbiting a supermassive black hole as Einstein predicted

ESO observations have revealed a star orbiting a supermassive black hole as Einstein predicted

The ESO has announced that observations made using its Very Large Telescope have shown for the first time that a star orbiting the supermassive black hole in the center of the Milky Way moves as Einstein predicted. According to the ESO, the star that's orbiting the blackhole moves just as predicted by Einstein's general theory of relativity. The orbit of the star is shaped like a rosette and not in an ellipse as predicted by Newton's theory of gravity.

Exoplanet with ‘extreme’ ultra-hot surface may rain iron droplets

Exoplanet with ‘extreme’ ultra-hot surface may rain iron droplets

The European Space Observatory's Very Large Telescope has discovered an exoplanet described as having an 'extreme' environment that may include raining iron. Researchers note that at its hottest temperatures, the planet's environment could vaporize metals, which then get carried by the winds into cooler regions, causing them to condense and then rain down as metal droplets.

NASA wants the public to help track light pollution from VLEO satellites

NASA wants the public to help track light pollution from VLEO satellites

NASA wants the public to help it track very-low Earth orbit (VLEO) satellites and the potential light pollution issues they may cause. The space agency launched a public science project that anyone can participate in, stating that it only requires a tripod, smartphone, and the use of a website that reveals when satellites will be overhead. Similarly, the European Space Observatory is also tracking these satellites for the same reason.

ESO says that the asteroid Hygiea could be a dwarf planet

ESO astronomers have used the SPHERE instrument on the Very Large Telescope to look at the asteroid called Hygiea. The observations have shown that Hygeia could be classified as a dwarf planet. The object is said to be the fourth-largest asteroid in the belts behind Ceres, Vesta, and Pallas.
