Astrophysicists Map Evolution of Binary Stars Using White Dwarf and Main Sequence Pairs
What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team of researchers from the United States and Canada investigated a binary star system comprised of white dwarfs and main sequence stars that…

‘Behemoth star’ captured in spectacular close-up image — and it’s on the brink of exploding
For the first time, astronomers have taken a high-quality, zoomed-in photo of a star outside our galaxy — and it’s right on the brink of exploding in a violent supernova. The new close-up image, captured by the European Southern Observatory’s (ESO) Very Large Telescope Interferometer (VLTI) in Chile, shows the red supergiant WOH G64, commonly…

Hubble Space Telescope Looks at Flocculent Spiral: NGC 2090
Astronomers using the NASA/ESA Hubble Space Telescope have captured an amazing new photo of the spiral galaxy NGC 2090. This Hubble image shows NGC 2090, a spiral galaxy some 40 million light-years away in the southern constellation of Columba. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions…

Astronomers see debris disk around young star Vega in unprecedented detail | University of Arizona News
In the 1997 movie “Contact,” adapted from Carl Sagan’s 1985 novel, scientist Ellie Arroway, played by Jodi Foster, takes a space-alien-built wormhole ride to the star Vega. She emerges inside a snowstorm of debris encircling the star – but no obvious planets are visible. According to a new paper by a team of astronomers at…

How a mini-team of NASA archivists is restoring astronomical history
Precious data from space missions, going back decades, is being carefully restored and archived by scientists at NASA’s Space Science Date Coordinated Archive, allowing researchers today to make new discoveries by delving into the history books. “What’s surprising is how much of this information is either lost or at least not in a condition that…

2-million-mile-per-hour galactic crash reawakens a dangerous ‘cosmic crossroads’
Using one of the most powerful telescopes on Earth, astronomers have witnessed an intimidating 2-million-mile-per-hour (3.2-million-kilometer-per-hour) smash-up between galaxies at a dangerous “cosmic crossroads,” the site of multiple previous collisions. The collision occurred when the galaxy NGC 7318b ripped through the site of previous galactic smash-ups, a galactic grouping called “Stephan’s Quintet.” The impact created…

Unusual black hole light bursts puzzle astronomers: ‘We are finding a lot of weird stuff’
Astronomers have stumbled upon a pair of massive black holes in a distant galaxy that are triggering unusual bursts of light. These bright emissions, which appear to peak on a regular cycle, may be caused by the black hole duo disrupting a massive gas cloud — a phenomenon researchers say is the first of its…

First Close Up Picture of Star Outside Our Galaxy Shows a Giant About to Blow
Astronomers zoomed in on a stellar behemoth in the Larger Magellanic Cloud, a galaxy that orbits about 160,000 light-years from the Milky Way. In a stunning scientific and technological feat, a group of astronomers said Thursday that it had managed to take the first close-up picture of a star in another galaxy. Not only was…
