Hubble Telescope sees a cosmic “gargoyle” in this dazzling new image

13 hours ago__ __Victor Tangermann__ __Filed under: Hard science Galactic “gargoyle” The Hubble Space Telescope has just captured a spectacular new image of two galaxies being dragged towards the center of another galaxy. The two galaxies NGC 2799 and NCG 2798 have already formed a “gargoyle” that shows how one galaxy drips individual stars like drops of water into the …

“Ten one-billionths of cosmic history” – Homo species of the past could not survive the intense climate change (weekend feature)

Posted on Oct 17, 2020 in Climate Change, Evolution, Science The human experience with our light blue dot “took less than 10 billionths of cosmic history, surrounded by a huge lifeless space, but we humans congratulate ourselves,” says Peter Brannen, author of Ends of the world on the current human domination, recently dubbed the Anthropocene – the 1950s atomic era …

NASA’s TESS creates a cosmic view of the northern sky

This mosaic of the northern sky contains 208 images captured by NASA’s Transiting Exoplanet Survey Satellite (TESS) in its second year of scientific activity in July 2020. The mission divided the northern skies into 13 sectors, each of which was imaged by the spacecraft’s four cameras for almost a month. Among the many notable celestial objects that are visible: the …

Galaxies trapped in the web of a supermassive black hole – The cosmic “spider web” made of gas extends over 300 times the size of the Milky Way

Artist’s impression of the network of the supermassive black hole. With the help of ESO’s Very Large Telescope (VLT), astronomers have found six galaxies around a supermassive black hole. Such a close grouping was first observed in the first billion years of the universe. This artist’s impression shows the central black hole and the galaxies enclosed in its gas network. …

Cosmic diamonds formed in gigantic planetary collisions

Artist’s impression of the collision of two protoplanets. Photo credit: NASA / SOFIA / Lynette Cook International research team solves the theory of how diamonds were formed in protoplanets. Geoscientists at Goethe University have found the largest extraterrestrial diamonds ever discovered in meteorites – nevertheless a few tenths of a millimeter in size. Together with an international team of researchers, …

How fast is the universe expanding? Measurement of cosmic expansion with radio astronomy and gravitational waves

Artist’s impression of the explosion and eruption of gravitational waves that occur when a pair of superdense neutron stars collide. New observations with radio telescopes show that such events can be used to measure the rate of expansion of the universe. Credit: NRAO / AUI / NSF How fast is the universe expanding? We don’t know for sure. Astronomers study …

The stunning Andromeda Galaxy and ‘Cosmic Inferno’ bring in the top prizes in the space photo contest

The Andromeda Galaxy is 2 million light years away earth, but it looks close enough to touch an image that took home the grand prize in the 2020 Royal Observatory Greenwich Insight Investment Astronomy Photographer of the Year competition. French photographer Nicolas Lefaudeux used a technique called tilt-shift, in which the lens of a camera was positioned to manipulate the …

Observations suggest a missing ingredient in the cosmic recipe

This Hubble space telescope shows the massive galaxy cluster MACS J1206. Embedded in the cluster are the distorted images of distant background galaxies, seen as arcs and smeared features. These distortions are caused by the amount of dark matter in the cluster, the gravity of which bends and magnifies the light of distant galaxies. This effect, known as gravitational lenses, …

The interstellar visitor Oumuamua could actually be a cosmic dust bunny

Since then it has been floating through our cosmic forest neck, the interstellar visitor ‘Oumuamua fascinated and confused scientists. Now a new theory has emerged that the cigar-shaped space rock could actually be a dust bunny. Here on earth, “dust bunnies” are clumps of accumulated dust and debris held together by static electricity that float under furniture pushed by the …
