Galaxies stop neighbors from growing by stealing gas from their hearts

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

Smoking gun of rare “zombie star” supernova discovered in Milky Way

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

Dark energy instrument snaps breathtaking image of galactic neighbor

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

Cold gas cloud in our galaxy could be hiding universe’s missing matter

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

New Horizons probe finds that space is darker than we thought

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

Evidence of “modified gravity” strengthens dark matter alternative

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 precisely trace distance to oldest and farthest known galaxy

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

Hubble gallery showcases 30 cosmic gems visible to amateur astronomers

NASA has released a collection of 50 stunning Hubble images to celebrate the veteran telescope’s 30th anniversary, which took place earlier this year. The images show 30 cosmic objects, ranging from planetary nebulae to galaxies in incredible detail, r… Continue reading Hubble gallery showcases 30 cosmic gems visible to amateur astronomers

New Gaia data reveals the motion of our galaxy in extravagant detail

ESA has made public a colossal data release from the agency’s Gaia observatory, which is currently engaged in a mission to survey 1 billion stars orbiting in the Milky Way. The data has already borne fruit, shedding light on the violent history of our … Continue reading New Gaia data reveals the motion of our galaxy in extravagant detail

Missing dark matter mystery reveals a galaxy entering death spiral

Astronomers are a step closer to solving a cosmic mystery, thanks to new Hubble data. Observations from the space telescope show a dwarf galaxy previously found to be missing most of its dark matter is being stripped of this matter by a larger nearby g… Continue reading Missing dark matter mystery reveals a galaxy entering death spiral
