Old star seen zooming through space at a speed of 600 kilometers per second

Most stars in the Milky Way move in quiet and orderly orbits around the galactic center, but that is not the case for all of them. Every now and then a maverick is caught breaking ranks, zooming along at speeds that will eventually launch him into intergalactic space. These ‘hypervelocity’ stars are extremely rare, but … Read more

Nova explosion from a nearby star will soon light up Earth’s sky

The vast expanse of the night sky, a canvas studded with countless stars, is about to reveal a rare and spectacular phenomenon. Brace yourself for a stellar light show as T Coronae Borealis, a seemingly inconspicuous star nestled in the Corona Borealis constellation, is on the verge of a dramatic nova explosion. T Coronae Borealis … Read more

To calibrate telescopes on Earth, NASA launches an ‘artificial star’ into orbit around Earth

a red-light hued domed observatory beams four lasers, violet, indigo, yellow and green, from an opening in its roof into the night sky which connect to a large satellite in the sky.

In 2029, sky watchers may catch a glimpse of at least one human-made ‘star’ in the sky. Earlier this week, NASA announced plans to place a small satellite in orbit just over 35,400 kilometers above our planet’s surface – far enough so that the satellite can mimic a real star for telescopes at Soil. Scientists … Read more

NASA will put a ‘new star’ in the sky by the end of this decade in the first mission of its kind

Stars spinning around an observatory in the night sky

A unique NASA mission aims to place a new ‘star’ in the sky by the end of this decade to help solve many of the universe’s greatest mysteries, scientists have announced. The Landolt NASA Space Mission aims to send an artificial stellar satellite into orbit by “early 2029.” Peter Plavchanan astronomer at George Mason University … Read more

Astronomers discover parallel disks and jets in a young binary star system

Astronomers Discover Parallel Disks And Jets In Young Binary Star System

Astronomers have made a groundbreaking discovery using NASA’s Atacama Large Millimeter/submillimeter Array (ALMA) and James Webb Space Telescope (JWST). They observed twoin disks and parallel jets erupting from a few young stars in the star system WL20, located more than 400 light-years away in the rho Ophiuchi molecular cloud complex. This unexpected finding provides new … Read more

It’s a twin! Webb Telescope reveals long-studied star is not one, but two, with massive jets streaming into space

Astronomers have had a big surprise with the discovery that a star known as WL 20S, which has been studied extensively since the 1970s, is actually not one but a pair of stars. The discovery of the surprising twin was made with the James Webb Space Telescope during a survey of a group of young … Read more

NASA’s Webb reveals long-studied star is actually a twin – NASA

WL20 group of stars is located in the Rho Ophiuchi star-forming region

Webb’s mid-infrared instrument, which was managed by NASA’s Jet Propulsion Laboratory until launch, also revealed jets of gas streaming into space from the twin stars. Scientists recently got a big surprise from NASA’s James Webb Space Telescope when they pointed the observatory at a group of young stars called WL 20. The region has been … Read more

Stellar fireworks: Hubble revisits the 40-year Nova mystery of a strange star

SciTechDaily

This artist’s concept shows the nova system HM Sagittae (HM Sge), where a white dwarf star is pulling material from its red giant companion. This forms a red-hot disk around the dwarf, which could unpredictably undergo a spontaneous thermonuclear explosion as the red giant’s hydrogen trap becomes denser and reaches a tipping point. These fireworks … Read more

‘Once-in-a-lifetime’ nova explosion will add a new star to the night sky in a dazzling spectacle: NASA

American news By means of Patrick Reilly Published June 12, 2024, 10:59 PM ET Scientists around the world are eagerly awaiting a cosmic nova event that NASA says will add a “new star” to the night sky sometime between now and September. The spectacle will be so bright that it will be visible to the … Read more
