NASA’s Webb Investigates Eternal Sunrises, Sunsets on Distant World

NeRD

6 Min Read NASA’s Webb Investigates Eternal Sunrises, Sunsets on Distant World Artists concept of WASP-39 b (full image below). Near-infrared spectral analysis of terminator confirms differences in morning and evening atmosphere Researchers using NASA’s James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked…

NeRD

6 Min Read Vivid Portrait of Interacting Galaxies Marks Webb’s Second Anniversary Webb’s view of the interacting galaxies of Arp 142 that combines Webb’s NIRCam and MIRI instrument images. Full image below. Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA’s James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a “parade” of discoveries by astronomers around the world. “Since President Biden and Vice President Harris unveiled the first image from…

Hubble Measures the Distance to a Supernova

NeRD

3 min read Hubble Measures the Distance to a Supernova This NASA/ESA Hubble Space Telescope image features the galaxy NGC 3810. ESA/Hubble & NASA, D. Sand, R. J. Foley Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. Beyond that, astronomers need to use…

Hubble Examines an Active Galaxy Near the Lion’s Heart

NeRD

2 min read Hubble Examines an Active Galaxy Near the Lion’s Heart This NASA/ESA Hubble Space Telescope features the elliptical galaxy Messier 105. ESA/Hubble & NASA, C. Sarazin et al. It might appear featureless and unexciting at first glance, but NASA/ESA Hubble Space Telescope observations of this elliptical galaxy — known as Messier 105 — show that the stars near the galaxy’s center are moving very rapidly. Astronomers have concluded that these stars are zooming around a supermassive black hole with an estimated mass of 200 million Suns! This black…

NASA Releases Hubble Image Taken in New Pointing Mode

NeRD

2 min read NASA Releases Hubble Image Taken in New Pointing Mode This NASA Hubble Space Telescope features the galaxy NGC 1546. NASA, ESA, STScI, David Thilker (JHU) NASA’s Hubble Space Telescope has taken its first new images since changing to an alternate operating mode that uses one gyro. The spacecraft returned to science operations June 14 after being offline for several weeks due to an issue with one of its gyroscopes (gyros), which help control and orient the telescope. This new image features NGC 1546, a nearby galaxy in…

Investigating the Origins of the Crab Nebula With NASA’s Webb

NeRD

6 Min Read Investigating the Origins of the Crab Nebula With NASA’s Webb This image by NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) shows different structural details of the Crab Nebula. New data revises our view of this unusual supernova explosion. A team of scientists used NASA’s James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that…

NASA’s Roman Mission Gets Cosmic ‘Sneak Peek’ From Supercomputers

NeRD

Researchers are diving into a synthetic universe to help us better understand the real one. Using supercomputers at the U.S. DOE’s (Department of Energy’s) Argonne National Laboratory in Illinois, scientists have created nearly 4 million simulated images depicting the cosmos as NASA’s Nancy Grace Roman Space Telescope and the Vera C. Rubin Observatory, jointly funded by NSF (the National Science Foundation) and DOE, in Chile will see it. Michael Troxel, an associate professor of physics at Duke University in Durham, North Carolina, led the simulation campaign as part of a…
