Astronomers Find 9,000-Light-Year-Long Wave-Shaped Structure in Milky Way

Jan 9, 2020 by Enrico de Lazaro

Using data from ESA’s Gaia star-mapping spacecraft, a team of astronomers from Austria and the United States has discovered a wave-shaped arrangement...

This composite image shows dense swirls of gas and dust in the central region of our Milky Way Galaxy. The image spans 600 light-years across and is helping astronomers learn how many massive stars are forming in the Galactic center. New data from SOFIA taken at 25 and 37 microns, shown in blue and green, are combined with data from ESA’s Herschel Space Observatory, shown in red (70 microns), and NASA’s Spitzer Space Telescope, shown in white (8 microns).

Astronomers using the Faint Object Infrared Camera for the SOFIA Telescope (FORCAST) instrument onboard NASA’s Stratospheric Observatory for Infrared...

This composite image shows thousands of star-forming galaxies in radio light and the MeerKAT radio telescope array in the South African Karoo semidesert. The brightest spots are luminous radio galaxies powered by supermassive black holes. The myriad faint dots are distant star-forming galaxies like our own Milky Way, too faint to have been detected before now. Because radio waves travel at the speed of light, this image is a time machine that samples the star formation history of the Universe. Image credit: SARAO / NRAO / AUI / NSF.

Taken with the HAWK-I instrument on ESO’s Very Large Telescope, this stunning image shows the Milky Way’s central region with an angular resolution of 0.2 arcseconds. The image combines observations in three different wavelength bands. Image credit: ESO / Nogueras-Lara et al.

VLT Observes Milky Way’s Central Region

Dec 16, 2019 by News Staff

Astronomers using ESO’s Very Large Telescope (VLT) have captured a stunning new image of the Milky Way’s densest region of stars, gas and dust, which...

This composite image shows the surroundings of a supermassive black hole that is triggering star formation across the longest distance ever seen; as hot gas swirls around the black hole, it emits large amounts of X-rays that Chandra detects; the black hole is also the source of radio-wave emission from a jet of high-energy particles -- previously detected by scientists with the VLA -- that stretches about a million light-years.
