Hubble Views a Galactic Supernova Site

NeRD

2 min read Hubble Views a Galactic Supernova Site This NASA Hubble Space Telescope image is of the small galaxy known as UGC 5189A. ESA/Hubble & NASA, A. Filippenko This image features a relatively small galaxy known as UGC 5189A, which is located about 150 million light-years away in the constellation Leo. This galaxy was observed by the NASA/ESA Hubble Space Telescope to study a supernova explosion in 2010 known as SN 2010jl. This particular supernova is notable because it was an exceptionally luminous supernova event. In fact, over a period of three years,…

Webb Shows Many Early Galaxies Looked Like Pool Noodles, Surfboards

NeRD

5 Min Read Webb Shows Many Early Galaxies Looked Like Pool Noodles, Surfboards Researchers are analyzing distant galaxies when the universe was only 600 million to 6 billion years old. Credits: NASA, ESA, CSA, Steve Finkelstein (UT Austin), Micaela Bagley (UT Austin), Rebecca Larson (UT Austin) Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we…

Hubble Finds Weird Home of Farthest Fast Radio Burst

NeRD

5 min read Hubble Finds Weird Home of Farthest Fast Radio Burst A NASA Hubble Space Telescope image of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble’s sensitivity and sharpness reveals a compact group of multiple galaxies that may be in the process of merging. They existed when the universe was only 5 billion years old. FRB 20220610A was first detected on June 10, 2022, by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope in Western Australia. The European Southern Observatory’s Very Large Telescope…

Meet the Infrared Telescopes That Paved the Way for NASA’s Webb

NeRD

Scientists have been studying the universe with infrared space telescopes for 40 years, including these NASA missions, from left: the Infrared Astronomical Satellite (IRAS), launched in 1983; the Spitzer Space Telescope, launched in 2003; and the James Webb Space Telescope, launched in 2021. NASA/JPL-Caltech The Webb telescope has opened a new window onto the universe, but it builds on missions going back 40 years, including Spitzer and the Infrared Astronomical Satellite. On Dec. 25, NASA will celebrate the two-year launch anniversary of the James Webb Space Telescope – the largest…

Hubble Sights a Galaxy with ‘Forbidden’ Light

NeRD

2 min read Hubble Sights a Galaxy with ‘Forbidden’ Light This NASA Hubble Space Telescope image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. ESA/Hubble & NASA, C. Kilpatrick This whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core known as an active galactic nucleus (AGN) and is categorized as a Type-2 Seyfert galaxy. Seyfert galaxies, along with quasars, host one of…

Life might have been possible just seconds after the Big Bang

NeRD

Life has found a home on Earth for around 4 billion years. That’s a significant fraction of the universe’s 13.77 billion-year history. Presumably, if life arose here, it could have appeared anywhere. And for sufficiently broad definitions of life, it might even be possible for life to have appeared mere seconds after the Big Bang. To explore the origins of life, first we have to define it. There are over 200 published definitions of the term, which shows just how difficult this concept is to grapple with. For example, are…

Hubble Views a Double Cluster of Glowing Galaxies

NeRD

2 min read Hubble Views a Double Cluster of Glowing Galaxies This NASA Hubble Space Telescope image of Abell 3192 holds two independent galaxy clusters. ESA/Hubble & NASA, G. Smith, H. Ebeling, D. Coe This Hubble image features a massive cluster of brightly glowing galaxies, first identified as Abell 3192. Like all galaxy clusters, this one is suffused with hot gas that emits powerful X-rays, and it is enveloped in a halo of invisible dark matter. All this unseen material – not to mention the many galaxies visible in this image –…
