Hubble Examines a Barred Spiral’s Light – NASA Science

The data in this image used a narrow-band filter that allowed H-alpha emission through to the telescope’s detectors. The particular filter, called F657N (F for filter, N for narrow, and 657 for the wavelength in nanometers) or the H-alpha filter, lets through light very close to the 656.46 nanometer H-alpha line’s wavelength. It reveals pinkish … Read more

Hubble Captures a Bright Spiral in the Queen’s Hair – NASA Science

NGC 4689 holds an interesting — albeit less royal — place in modern astronomy. The universe is so incredibly vast that at a distance of 54 million light-years NGC 4689 is relatively nearby for a galaxy. This image includes data from two sets of observations, one made in 2019, the other in 2024 , and … Read more

Hubble Views a Galaxy with a Voracious Black Hole – NASA Science

Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It’s classified as a Seyfert galaxy, which means that it’s an extremely energetic type of galaxy with an active galactic nucleus (AGN). However, Seyfert galaxies are unique from other sorts of AGNs because the galaxy itself can still be … Read more

Hubble Hunts Visible Light Sources of X-Rays – NASA Science

The image is from an observation program dedicated to the study of dwarf galaxies in the Virgo cluster that is searching for the visible light emissions from sources of X-rays in these galaxies. X-rays are often emitted by accretion discs, where material that is drawn into a compact object by gravity crashes together and forms … Read more

Hubble Spots a Magnificent Barred Galaxy – NASA

The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barred spiral galaxy is a similar size to our Milky Way at 100,000 light-years across. Many stars are concentrated in its … Read more

Hubble Captures a Bright Galactic and Stellar Duo – NASA Science

This image from the NASA/ESA Hubble Space Telescope features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than galaxy clusters … Read more

Hubble Spots a Galaxy Hidden in a Dark Cloud

However, we can’t fully appreciate the features of this galaxy — at least in visible light — because it’s partially concealed by a stretch of dark dust (lower-right third of the image). This dark nebula is part of the Chamaeleon star-forming region, itself located only around 500 light-years from us, in a nearby part of … Read more

NASA’s Webb Probes an Extreme Starburst Galaxy

On the left is the starburst galaxy M82 as observed by NASA’s Hubble Space Telescope in 2006. The small box at the galaxy’s core corresponds to the area captured so far by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope. The red filaments as seen by Webb are the polycyclic aromatic hydrocarbon … Read more

Spiral Galaxy NGC 4254’s Dazzling Swirls – NASA

NGC 4254, a spiral galaxy, is resplendent in orange and blue in this Jan. 29, 2024, image from the James Webb Space Telescope. This is one of 19 nearby spiral galaxies recently imaged by the telescope as part of the long-standing Physics at High Angular resolution in Nearby GalaxieS (PHANGS) program supported by more than … Read more
