Astronomers using ESO's SPHERE instrument at the Very Large Telescope (VLT) have revealed that the asteroid Hygiea could be classified as a dwarf planet. The object is the fourth largest in the asteroid belt after Ceres, Vesta, and Pallas. For the first time, astronomers have observed Hygiea in sufficiently high
The Hubble Space Telescope has captured the best pictures yet of our newest interstellar visitor.This comet from outside our solar system is zooming by us at a blistering 110,000 mph (177,000 kph). Hubble caught some glam shots over the weekend from a distance of 260 million miles (420 million kilometers).
A huge one-off burst of mysterious cosmic radio waves has been precisely located to a galaxy 3.6 billion light years away. The powerful shiver of waves came from a Milky Way-sized galaxy that scientists were able to pinpoint for the first time using three of the world’s largest optical telescopes.“This is the big breakthrough that
In the course of looking for possible signs of Extra-Terrestrial Intelligence (ETI), scientists have had to do some really outside-of-the-box thinking. Since it is a foregone conclusion that many ETIs would be older and more technologically advanced than humanity, those engaged in the Search for Extra-Terrestrial Intelligence (SETI) have to
The Hubble Space Telescope has captured a spectacular image showing a vast collection of galaxies located around 4 billion light-years from Earth.The cluster, known as Abell 370—located in the constellation Cetus—is the first target of a new Hubble mission known as the BUFFALO survey, which aims to broaden our understanding of
A new report mandated by the US Congress recommends that NASA should embark on a new tranche of exoplanet missions to determine if the solar system is a rarity and whether life exists elsewhere in the universe. The "Exoplanet Science Strategy" report by the National Academies of Sciences, Engineering, and
Around sunrise on Feb. 15, 2013, an extremely bright and otherworldly object was seen streaking through the skies over Russia before it exploded about 97,000 feet above the Earth's surface. The resulting blast damaged thousands of buildings and injured almost 1,500 people in Chelyabinsk and the surrounding areas. While this
