NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies

NeRD

6 Min Read NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies Webb’s set of 19 PHANGS images of face-on spiral galaxies. Credits: NASA, ESA, CSA, STScI, Janice Lee (STScI), Thomas Williams (Oxford), and the PHANGS team It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes. Only NASA’s James Webb Space Telescope can deliver highly detailed scenes of nearby galaxies…

NASA Collaborating on European-led Gravitational Wave Observatory in Space

NeRD

4 min read NASA Collaborating on European-led Gravitational Wave Observatory in Space The LISA (Laser Interferometer Space Antenna) mission, led by ESA (European Space Agency) with NASA contributions, will detect gravitational waves in space using three spacecraft, separated by more than a million miles, flying in a triangular formation. Lasers fired between the satellites, shown in this artist’s concept, will measure how gravitational waves alter their relative distances. AEI/MM/Exozet The first space-based observatory designed to detect gravitational waves has passed a major review and will proceed to the construction of…

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…

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…

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…
