Astronomy 2016-10-13T00:00:00Z But the flare that Dr. Graham’s group saw came from a galaxy about 8 billion light-years away, about half as far as the gravitational wave event GW190521, casting their identification of the source in doubt.

How Astronomers Revolutionized Our View of the Cosmos 2020-09-01T04:00:00Z Now, it's discovered evidence of a supernova 2,400 light-years away that looks like an orange ribbon. Hubble finds dead star in deep space that resulted in an orange shockwave 2020-09-01T04:00:00Z The swathes of gas are so large they extend nearly two light-years from its center. Astronomers spot glowing 'butterfly' in deep space 2020-08-04T04:00:00Z The radius of the ring is approximately 0.75 light-year from the supernova location. Astronomy 2016-10-13T00:00:00Z The event unfolded at an almost unimaginable distance from Earth — in a spot that is now 17 billion light-years away according to standard cosmological calculations that describe an expanding universe. These Black Holes Shouldn’t Exist, but There They Are 2020-09-02T04:00:00Z Named TYC 8998-760-1 and located about 300 light-years from Earth in the constellation Musca, the star is similar in mass to the sun. Scientists Unveil First Ever Pictures of Multiple Planets around a Sunlike Star 2020-07-24T04:00:00Z This baby sun and its two giant gas planets are fairly close by galactic standards at 300 light-years away. Telescope snaps family portrait of 2 planets around baby sun 2020-07-22T04:00:00Z A light-year, which measures distance in space, is the equivalent of nearly 6 trillion miles. Astronomers spot glowing 'butterfly' in deep space 2020-08-04T04:00:00Z Because interstellar dust absorbs the light from stars, Herschel could see only those stars within about 6000 light-years of the Sun. Astronomy 2016-10-13T00:00:00Z The new paper was based on measurements, performed by Dr. Tully and his colleagues, of the distances of 18,000 galaxies as far away as 600 million light-years. Beyond the Milky Way, a Galactic Wall 2020-07-10T04:00:00Z A portion of the new map of the Universe's cosmic microwave background radiation, representing a region of space 20 billion light-years across.Credit: Mystery over Universe’s expansion deepens with fresh data 2020-07-14T04:00:00Z Researchers at Kyoto University and the National Astronomical Observatory of Japan detected 12 stellar flares on AD Leonis, a red dwarf 16 light-years away. Gigantic 'superflare' spotted on nearby star 2020-07-13T04:00:00Z About 780 million years ago — and 780 million light-years away — it was eaten by a black hole 23 times more massive than the sun. A Black Hole’s Lunch Provides a Treat for Astronomers 2020-06-24T04:00:00Z The brightest part of the Galaxy consists of a thin, circular, rotating disk of stars distributed across a region about 100,000 light-years in diameter and about 2000 light-years thick.
