Astronomers believe they may have discovered the brightest star in the Milky Way amid a swirling cloud of colourful stellar dust. 0 comments edit related share scienceNicknamed the 'Peony nebula star', the celestial body blazes with the light of 3.2million suns in the centre of our galaxy. picked by AutumnLotus 1 year ago |
Astronomers using the Hubble Space Telescope and W. M. Keck Observatory have found a lopsided debris disk around a young star known as HD 15115. As seen from Earth, the edge-on disk resembles a needle sticking out from the star. picked by AutumnLotus 2 years ago 2 comments edit related share plime.com |
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. picked by AutumnLotus 2 years ago 0 comments edit related share science |
University of Arizona astronomers who are probing the oxygen-rich environment around a supergiant star with one of the world's most sensitive radio telescopes have discovered a score of molecules that include compounds needed for life. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
Astronomers have used light echoes from a supernova explosion as a time machine to look again at a historic stellar event first witnessed on Earth more than 400 years ago. The brilliant 'new star' appeared in the sky in 1572 and was so bright it could be seen during the day. It was observed and charted by astronomer Tycho Brahe who discovered it was far away from the moon. picked by AutumnLotus 12 months ago 0 comments edit related share science |

About 140 years ago, our time, a stellar explosion lit up our galaxy with a blinding flash of light, sending out powerful shock waves to boot. Now, astronomers have spotted the youthful remains from the explosion. picked by AutumnLotus 2 years ago 0 comments edit related share science |
Astronomers have spotted evidence of a second Earth being built around a distant star 424 light-years away. Using NASA's Spitzer Space Telescope, astronomers have spotted a huge belt of warm dust swirling around a young star called HD 113766 that is just slightly larger than our sun. picked by AutumnLotus 2 years ago 4 comments edit related share plime.com |
An international team, led by astronomers at the University of Hertfordshire in the UK, have discovered one of the coolest sub-stellar bodies ever found outside our own solar system, orbiting the red dwarf star Wolf 940, some 40 light years from Earth. picked by AutumnLotus 7 months ago 0 comments edit related share plime.com |
Using observations from ESO's VLT, astronomers were able for the first time to reconstruct the site of a flare on a solar-like star located 150 light years away. The study of this young star, nicknamed 'Speedy Mic' because of its fast rotation, will help scientists better understand the youth of our Sun. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
US astronomers have discovered the biggest black hole orbiting a star 1.8 million light-years from Earth in the constellation Cassiopeia, with a record-setting mass of 24 to 33 times that of our Sun. The massive newcomer beats the previous stellar-mass black hole discovered October 17 in the M33 galaxy that has 16 times the mass of our Sun. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
A tiny star recently unleashed what is considered the brightest burst of light ever seen in the universe from a normal star. Shining with only 1 percent of the sun's light and boasting just a third of the sun's mass, this run-of-the-mill star previously was nothing to write home about. picked by AutumnLotus 2 years ago 0 comments edit related share science |
A massive young star seems to have exploded before its time, new Hubble Space Telescope images reveal. The star, the heftiest to have been linked to a supernova explosion, could challenge models of when stellar furnaces end their lives. picked by AutumnLotus 8 months ago 2 comments edit related share science |
An explosive star within our galaxy is showing signs of an impending eruption, at least in a cosmic time frame, and has for quite some time. From 1838 to 1858, the star called Eta Carinae brightened to rival the light of Sirius, the brightest star in the sky, and then faded to a dim star. Since 1940 it has been brightening again, and scientists think Eta Carinae will detonate in 10,000 to 20,000 y... read full post picked by AutumnLotus 2 years ago 0 comments edit related share science |

A large star in its death throes is leaving a huge, turbulent tail of oxygen, carbon and nitrogen in its wake that makes it look like an immense comet hurtling through space. picked by AutumnLotus 2 years ago 1 comments edit related share plime.com |
Astronomers are baffled after finding an exotic type of star called a pulsar apparently locked in an elongated orbit around a star much like the sun -- an arrangement defying what had been known about such objects. picked by AutumnLotus 2 years ago 1 comments edit related share science |
In a distant galaxy, a star orbiting a massive central black hole strays too close to the insatiable giant and is torn apart. But before it can be devoured, the star lets out one last scream in a flare of light that slowly echoes across the galaxy. Astronomers on Earth pick up this faint call and use it to map the nucleus of the galaxy from which it emanated. picked by AutumnLotus 2 years ago 0 comments edit related share science |

An unusual star may have swallowed its stellar companion and burped out a planet-forming cloud as a result, a new study reports. The star, called BP Piscium, is surrounded by a thick disc of gas and dust from which it appears to be sucking up new material at a prodigious rate. picked by AutumnLotus 2 years ago 0 comments edit related share science |
