The world's most powerful space telescope captured an image of the NGC 2835 galaxy, known as "Eye of the Serpent." It's 35 million light-years away.
An ancient galaxy called SPT0418–47 has been found near the edge of the observable Universe. This family of stars looks much like the Milky Way — and that is what makes this discovery so surprising — galaxies from the early Universe are supposed to look different than they do today. Formed just 1.4 billion years after the Big Bang, light from this far-flung galaxy took 12 billion years to reach Earth. The body was discovered in 2020 by astronomers at the South Pole Telescope (SPT). Researchers found SPT0418–47 likely has a disk surrounding a central bulge like our own galaxy,… This story continues at The Next Web
The Magellanic Stream is a ribbon of gas that wraps around our home galaxy, but its origin story has been elusive.
The Hubble Space Telescope team has released another stunning space image captured by the instrument -- this one of a globular cluster called NGC 1805.
A magnificent cloud of diffuse halo of plasma surrounding our galactic neighbor, Andromeda, was recently mapped by astronomers using the Hubble Space Telescope. This envelope of electrically-charged particles stretches 1.3 million light years from it’s home galaxy, halfway to the Milky Way. In some places, Andromeda’s halo stretches two million light years from its parent galaxy, two-thirds of the way to our home galaxy. This close proximity means that Andromeda, destined to collide with the Milky Way in several billion years, has made “first contact” with our home galaxy. Halo… halo… halo… is there anybody out there? The halo was found… This story continues at The Next Web
It’s called the Galactic Center GeV Excess (GCE), and it’s not what we’d expected. New research into the GCE suggests that the glow isn’t what the as-yet best explanation of said glow was expected to be. First discovered by the Fermi Gamma-ray Space Telescope in 2009, it was expected that the GCE glow was the result of an annihilation of … Continue reading
Hubble Space Telescope observed the huge structure around our nearest galaxy
NASA has used the Hubble Space Telescope to map a complex, layered structure with two nested gas shells that surround the Andromeda spiral galaxy. Andromeda nearest major galaxy to the Milky Way. While Andromeda can be seen in the nighttime sky during autumn in the northern hemisphere, we can’t see is a vast halo of hot, rarefied gas that surrounds … Continue reading
Well, halo, halo Andromeda sports a ginormous halo of gas with a mass greater than 100 billion Suns that stretches from its outer edges up to two million light-years – a distance that reaches more than halfway to our own Milky Way galaxy.…
A newly published study suggests there could be more "rogue" planets, those that do not orbit a star, than there are stars in the Milky Way galaxy.
A new estimate suggests the Milky Way contains more free-floating planets than stars.
Earth may have spent the last 33,000 years drifting through what’s left of huge supernova explosions, scientists have theorized, going deep into the ocean for evidence of one of the most mysterious known substances. Samples of iron-60, a radioactive isotope generated by supernovas, have been discovered on the ocean floor, a faint reminder of dying stars. Iron-60’s radioactivity makes it … Continue reading
A group of citizen scientists has discovered 95 "cool worlds" near the sun, celestial objects much larger than planets but lighter than stars, known as brown dwarfs, according to a new study.
