The Sun emitted a strong solar flare, which peaked at 6:54 am UT on May 10, 2024. The Solar Dynamics Observatory, which observes the Sun constantly, captured an image of this event, as seen in the bright flash towards the center of the image. Solar flares are powerful explosions of energy that can affect radio communications, electrical power grids, navigation signals and..... #astronomy#space#astrophysics#astrophotography

This scattered collection of stars is actually an irregular dwarf galaxy called Holmberg IX. It resides just off the outer edge of Messier 81, a large spiral galaxy located 11.8 million light years from the Milky Way and located in the direction of the Ursa Major constellation. This image taken by the Space Telescope shows that Holmberg IX belongs to a type of..... #astronomy#space#astrophysics#astrophotography
A massive cotton candy-like exoplanet stumps astronomers.
@popsci reports on a new study from Nature Astronomy: "Despite being 50 percent bigger than the gas giant Jupiter, exoplanet WASP-193b is seven times less dense."
Sh2-114, also cataloged as LBN 347, is a very faint emission nebula visible in the Cygnus constellation, embedded in a much larger structure cataloged as LBN 346. This bundle of filaments seen here in a detailed wide-field image, collaboration between astronomers Tom Masterson and Kim Quick, are known as the Flying Dragon Nebula. It is a cloud that has..... #astronomy#space#astrophysics#astrophotography

Arp 238 is a pair of spiral galaxies that interact dramatically. The interaction consists of Arp 238A at the bottom of the image, and Arp 238B at the top. The two galaxies are linked by a bridge of material extracted from the outer disks of the galaxies, producing two highly curved tidal tails composed of gas and stars. Both galaxies show dust lanes at..... #astronomy#space#astrophysics#astrophotography
This image taken by the Hubble Space Telescope shows NGC 3783, a bright barred spiral galaxy located in the direction of the Centaurus Constellation and located at a distance of about 130 million light years from the Milky Way, which also lends its name to the NGC 3783 Galaxy Group. Like galaxy clusters, galaxy groups are small, gravitationally bound..... #astronomy#space#astrophysics#astrophotography
This year, there will be a nova, before or by September, as bright as the North Star.
After peak brightness it will remain bright enough, for several days, to observe with binoculars.
You can help research scientists with observational details.
"The sun sits alone at the center of our solar system — but it was actually born in a giant cloud alongside thousands of other stars. So where did all those stars go?"
Astrophysicists Jeremy Webb and Natalie Price-Jones explain what may have happened to the sun's siblings in a comic series for @NPR
1/ Most massive stellar #BlackHole in our galaxy found! With 33 times the mass of the Sun, this is the most massive black hole formed after the collapse of a star that we've found so far in the #MilkyWay.
ESA's Gaia mission found it via the wobble it induces on a star orbiting it, and data from ground-based telescopes helped confirm its mass and elucidate how it formed.
"[A] team of NASA researchers proposed how spacecraft could search for evidence of additional physics within our Solar System. This search, they argue, would be assisted by the spacecraft flying in a tetrahedral formation and using interferometers. Such a mission could help resolve a cosmological mystery that has eluded scientists for over half a century."
These are the targets of a spectrophotometry study of small Neptunian and Uranian moons using JWST, to characterize their surface compositions, by M. Belyakov and co-authors https://arxiv.org/abs/2404.06660
The Perseverance Mars rover, which explores the surface of Mars, used its cameras to capture the silhouettes of Phobos and Deimos as they transit in front of the Sun. Phobos passed in front of the Sun on February 8, 2024 and Deimos posed for Perseverance on January 19 2024. Both Phobos and Deimos had already been photographed during..... #astronomy#space#astrophysics#astrophotography
Looking towards the Sculptor Constellation at a distance of about 75 million light-years from the Milky Way is this giant spiral galaxy called NGC 289.
