By analyzing data from ESA's XMM-Newton spacecraft and NASA's TESS telescope, German astronomers have inspected a highly variable polar known as V496 UMa. Results of the study, published May 20 on arXiv.org, deliver more ...
This new NASA Hubble Space Telescope image looks at one of the nearest, massive lenticular galaxies to Earth, NGC 1023 some 36 million light-years away. Lenticular galaxies get their names from their edge-on appearance that ...
