"Unveiling the Cosmic Puzzle: Hubble's Discovery of a Fast Radio Burst Amidst Galaxies in the Throes of Merger"

-





 Hubble looked halfway back to the big bang in order to find the brightest and farthest fast radio burst to date.

Called FRBs, these are extremely powerful bursts of energy that can briefly outshine an entire galaxy. Not much is known about the cause of FRBs, but they could be triggered by something involving extreme physics – such as the collision of black holes or neutron stars.



However, this particular FRB was located within a compact group of galaxies that may be in the process of merging. It took Hubble's sharp and sensitive vision to pinpoint exactly where the FRB came from.Shared today during the American Astronomical Society's winter meeting (#AAS243), this unexpected FRB location may help astronomers solve the mystery of these enigmatic events.

Image description: This first image shows a field of blue, red, orange, yellow, and white distant galaxies against the black backdrop of space. The second image is the same, except at center a white inset box labeled “Host galaxy of FRB 20220610A” zooms in on a tight group of several galaxies of various elliptical shapes (to the far right). The white arrow inside the inset box points to the host galaxy of the exceptionally powerful fast radio burst 20220610A detected inside this galaxy group.

                       As part of NASA’s Commercial Lunar Payload Services initiative, Astrobotic’s Peregrine lander launched on United Launch Alliance’s (ULA) Vulcan rocket at 2:18 a.m. EST from Launch Complex 41 at Cape Canaveral Space Force Station in Florida .                  Carrying  NASA scientific instruments   as part of its Commercial Lunar Payload Services initiative, Astrobotic’s Peregrine lander launched on United Launch Alliance’s (ULA) Vulcan rocket at 2:18 a.m. EST from Launch Complex 41 at Cape Canaveral Space Force Station in Florida. Peregrine has about a 46-day journey to reach the lunar surface. Once on the Moon, NASA instruments will study the lunar exosphere, thermal properties of the lunar regolith, hydrogen abundances in the soil at the landing site, and conduct radiation environment monitoring. The five NASA science and research payloads aboard the lander will help the agency better understand planetary processes and evolution, search for evidence of water an

Taurid meteor shower 2024: When, where & how to see it

  Viewing conditions for the Taurids are good for the Southern Taurids but may wash out the Northern Taurids this year.                           A Taurid meteor over lake Simcoe, Canada, with the aurora borealis shimmering below, on Nov. 9, 2015.  (Image credit:   Orchidpoet via Getty   images)      The Taurid meteor shower is composed of two streams: The Southern Taurids which peak on Nov.         5; and the Northern Taurids which peak on Nov. 12 according to the   American Meteor Societ y These showers produce infrequent, slow and long-lasting  meteors  associated with comet Encke, a small comet with a nucleus measuring approximately 2.98 miles (4.8 km) in   diameter.    Viewing conditions for the 2024 South Taurid meteor shower will be good as the moon will    be about 15% illuminated at the time of the peak. But for the North Taurid meteor shower,      the moon will be 84% illuminated and will outshine fainter meteors.   "The Taurids are rich in fireballs, so if you see a Tau

What do you see? 🌌

  Invisible to our eyes, X-rays emitted by the hot gas that fills much of the Universe can shed light on many cosmic mysteries. The 'first light' observations of this gas by @jaxajp's X-Ray Imaging and Spectroscopy Mission (XRISM) are now ready. They demonstrate that the mission will play a big role in unveiling the evolution of the Universe and the structure of spacetime. The first test image is a wide view of a nearby cluster of galaxies called Abell 2319. In purple we see X-ray light from million-degree gas that permeates between the galaxies in the cluster. Observing this gas helps astronomers measure the total mass of the galaxy cluster, revealing information about the birth and evolution of the Universe. The image from XRISM (shown in purple) has been overlaid on a visible-light image from a ground-based telescope.The second colourful shot shows the remains of a massive star exploding in the nearby Large Magellanic Cloud. The different colours indicate different energ
