Most Precise Test of Einstein’s General Relativity Outside Milky Way

Most Precise Test of Einstein’s General Relativity Outside Milky Way
Astronomers using the VLT in Chile, and the NASA/ESA Hubble Space Telescope, have made the most precise test yet of Einstein’s general theory of relativity outside the Milky Way. The nearby galaxy ESO 325-G004 acts as a strong gravitational lens, distorting light from a distant galaxy behind it to create an Einstein ring around its centre. By comparing the mass of ESO 325-G004 with the curvature of space around it, the astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity. This rules out some alternative theories of gravity.

Exiled Asteroid Discovered in Outer Reaches of Solar System

Carbon Rich Asteroid in Kuiper Belt
ESO astronomers have investigated a relic of the primordial Solar System. The unusual Kuiper Belt Object 2004 EW95 is a carbon-rich asteroid, the first of its kind to be confirmed in the cold outer reaches of the Solar System. It has most likely formed in the asteroid belt between Mars and Jupiter and later flung billions of kilometres from its origin to its current home in the Kuiper Belt

Dead Star Circled by Light

Dead Star Circled by Light 
Spectacular new pictures, created from images from both ground- and space-based telescopes, tell the story of the hunt for an elusive missing object hidden amid a complex tangle of gaseous filaments in the Small Magellanic Cloud, about 200 000 light-years from Earth.

  Closest Temperate World Orbiting Quiet Star Discovered

Closest Temperate World Orbiting Quiet Star Discovered 
A temperate Earth-sized planet has been discovered only 11 light-years from Earth using ESO’s unique planet-hunting HARPS instrument. The new world has been designated Ross 128b and is now the second closest temperate planet so far detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO’s Extremely Large Telescope, which will be able to search for biomarkers in the planet's atmosphere.

Best Ever Image of a Star’s Surface and Atmosphere
Quite amazing is the new VLT Interferometer imager where astronomers have constructed the most detailed picture ever of a star, the red supergiant Antares. They have also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in Antares’s huge extended atmosphere. 

Dazzling Spiral with an Active Heart
Magnificent face-on view of the barred spiral galaxy Messier 77. The image does justice to the galaxy’s beauty, showcasing its glittering arms criss-crossed with dust lanes.This impressive luminosity is caused by intense radiation blasting out from a central engine — the accretion disc surrounding a super massive black hole. Material that falls towards the black hole is compressed and heated up to incredible temperatures, causing it to radiate a tremendous amount of energy.
