astronomy newsThis Hubble image taken by University of Virginia astronomer Craig Sarazin of the nearby elliptical galaxy Messier 105 (also called NGC 3379) is at present the Hubble Space Telescope Picture of the Week (January 7 – 11). A composite image exhibiting the distribution of darkish matter, galaxies and sizzling fuel in a merging galaxy cluster taken with NASA’s Hubble Space Telescope and with the Canada-France-Hawaii Telescope in Hawaii. Since Galileo’s time, astronomy has made nice strides, but, surprisingly, as late as the 1920’s, astronomers have been nonetheless debating about whether different galaxies have been simply close by nebulae, or in the event that they have been faraway “island universes,” made up of billions of stars. The first planets exterior our Solar System were not found until 1991, and we didn’t discover any planets round normal stars until 1995.

The EHT links telescopes around the globe to type an Earth-sized digital telescope with unprecedented sensitivity and backbone [three]. The EHT is the results of years of worldwide collaboration, and provides scientists a brand new way to research probably the most extreme objects within the Universe predicted by Einstein’s general relativity in the course of the centennial yr of the historic experiment that first confirmed the idea [4]. Astronomers using ESO’s SPHERE instrument at the Very Large Telescope (VLT) have revealed that the asteroid Hygiea could be categorised as a dwarf planet. The object is the fourth largest within the asteroid belt after Ceres, Vesta and Pallas.

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based mostly radio telescopes solid by way of international collaboration — was designed to seize images of a black gap. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the primary direct visible proof of a supermassive black hole and its shadow. New examine demonstrates for the first time that adjustments in cognitive efficiency correlate with changes in mind construction in NASA astronauts following spaceflight. Scientists model how the ‘weather’ on a star impacts exoplanets to see if even these thought to be in liveable zones could suffer from photo voltaic storms.

Scientists simulate early galaxy formation in a universe of darkish matter that is ultralight, or “fuzzy,” somewhat than cold or heat. An alien super-world 110 gentle years away from us is the first outdoors our photo voltaic system to have situations which are potentially suitable to host life, astronomers say. Australia’s emerging area industry is trying to the moon and Mars, however it additionally has a very practical benefit for farmers working in the soils of planet Earth. Thompson and his colleagues looked for proof of these black holes within the proposed objects’ stellar companions.

February 23, 2016 • Scientists had been studying the properties of the sunshine coming from a quasar — one of many brightest objects in the universe — when the light simply appeared to wink out. Now they think they know why. April 6, 2016 • A black gap with about 17 billion occasions the mass of our sun has turned up in one other remote galaxy. Astronomers now think these mass-eating monsters will not be so rare in any case.

Thuan’s colleagues on the research are astronomers Yuri Izotov and Natalia Guseva of the Ukrainian National Academy of Sciences, and graduate pupil Sandy Liss of UVA. The group found that a considerable fraction (eighty%) of the stellar mass of the galaxy was formed just a few million years in the past, making this probably the greatest counterparts found of primordial galaxies.
