Collaborate Disseminate
Astronomers have discovered the aftermath of a cosmic hit-and-run in our own galactic neighborhood. While studying the closest star cluster to the Sun, ESA scientists realized that it may have been disrupted by a huge lump of invisible mass, possibly d… Continue reading Dark matter drive-by may have disrupted closest star cluster to Earth
On a scale that’s hard to fathom, the universe is made up of a “cosmic web” of hydrogen filaments that feed and form galaxies. Now, astronomers have made the first direct observations of light from this web, by staring at a patch of sky with a powerful… Continue reading Glow of “cosmic web” filaments directly imaged for the first time
Moons orbit planets, planets orbit stars, and stars in galaxies orbit supermassive black holes. And that’s more or less where the chain ends, because the super masses involved tend to anchor those black holes in place. But now, researchers have found e… Continue reading “Restless” supermassive black hole may be wandering round its galaxy
Massive galaxies may be siphoning off star-forming material from the very hearts of smaller satellite galaxies, according to the results of a newly published study. The interaction causes the smaller cosmic structures to stagnate and essentially cease … Continue reading Galaxies stop neighbors from growing by stealing gas from their hearts
Astronomers have identified the remains of a rare type of supernova in our home galaxy for the first time. These events, known as Type Iax supernovae, occur when white dwarfs explode and may leave behind a “zombie star.”Continue ReadingCategory: Space,… Continue reading Smoking gun of rare “zombie star” supernova discovered in Milky Way
Astronomers have captured a stunning image of one of the Milky Way’s neighboring spiral galaxies. The portrait was taken using an instrument that was first created to hunt down dark energy – the enigmatic, invisible force that may be responsible for ac… Continue reading Dark energy instrument snaps breathtaking image of galactic neighbor
By studying the twinkling of stars, astronomers in Australia have discovered a huge cloud of cold gas in our galaxy, not far from Earth. This invisible mass could provide new hints about where to find the universe’s missing matter.Continue ReadingCateg… Continue reading Cold gas cloud in our galaxy could be hiding universe’s missing matter
How many galaxies are there in the observable universe? Not as many as we thought, according to a new study. NASA’s New Horizons probe has measured the blackness of the sky and found that there’s probably “only” a few hundred billion galaxies glowing t… Continue reading New Horizons probe finds that space is darker than we thought
Dark matter is currently the most widely accepted hypothesis for explaining some of the weirdness we see in the cosmos – but it’s not the only possibility. Now, a team of astronomers has discovered evidence in over 150 galaxies for a long-standing alte… Continue reading Evidence of “modified gravity” strengthens dark matter alternative
Astronomers have more accurately measured the distance to the oldest and farthest galaxy ever detected. The light they’re seeing left the galaxy, known as GN-z11, around 13.4 billion years ago, when the universe was a cosmic toddler, and this galaxy ma… Continue reading Astronomers precisely trace distance to oldest and farthest known galaxy
