Brunier Posted on September 30, 2023 September 30, 2023 by Brian Koberlein The Milky Way's Mass is Much Lower Than We Thought How massive is the Milky Way It’s an easy question to ask , but a difficult one to answer . Imagine a single cell in your body trying to determine your total mass , and you get an idea of how difficult it can be . Despite the challenges , a new study has calculated an accurate mass of our galaxy , and it’s smaller than we . thought One way to determine a galaxy’s mass is by looking at what’s
A new study shows how existing observatories like the ESO's Very Large Telescope (VLT) can be upgraded to perform cutting-edge astronomy

But it’s not today . Today , we can lose ourselves in the space telescope’s engrossing image of NGC 6822, also called Barnard’s Galaxy . Barnard’s Galaxy was discovered by the accomplished American astronomer E . E . Barnard in 1884. He spotted it with a 6-inch
By analyzing the data from the WALLABY pre-pilot survey, astronomers from the University of Western Australia and elsewhere, have inspected 78 candidate ultra-diffuse galaxies in the Eridanus supergroup. The study was detailed in a paper published September 21 on the pre-print server arXiv.
By conducting a blind search for large amplitude mid-infrared variables in the Wide Infrared Sky Explorer (WISE) archive, Chinese astronomers have serendipitously discovered a giant mid-infrared outburst from a distant young stellar object designated J064722.95+031644.6. The finding is reported in a paper published September 20 on the pre-print server arXiv.
Astronomers have reported the discovery of a new galaxy using the James Webb Space Telescope (JWST) as part of the JWST COSMOS-Web survey. The newfound object, designated JWST-ER1 is a massive and compact quiescent galaxy. The findings were detailed in a paper published September 14 on the pre-print server arXiv.
A trio of astrophysicists with Harvard and Smithsonian's Center for Astrophysics has found via computer modeling that the likely reason for the warp and flare of the Milky Way galaxy is a tilt of the dark halo. In their paper published in the journal Nature Astronomy, Jiwon Jesse Han, Charlie Conroy and Lars Hernquist describe their theories regarding the shape of the Milky Way galaxy and what their model showed.
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a distant star. The newfound alien world, designated TOI-1420 b, has an exceptionally low density. The finding is reported in a paper published September 18 on the pre-print server arXiv.
