Roman joins an international cohort of teamworking telescopes. Roman will work in tandem with many other NASA-led and international missions to provide the most complete view of our universe yet. Roman’s large panoramas will uncover interesting targets that Hubble could follow up on using infrared, visible, and ultraviolet light to offer a more comprehensive view.
A team of astronomers has just detected the fastest star in the galaxy. Its anomalous speed has a more unsettling explanation: It orbits Sagittarius A*, the supermassive black hole at the center of the Milky Way, the mass of which is equivalent to four million times that of the sun. S301, as astronomers have named
When Soundgarden Wrote “Black Hole Sun,” they may have inadvertently been onto something. In a new paper in Nature, scientists have chronicled a “black hole star” that’s the size of our solar system and glows bright red in the depth of space. The findings are based on observations from the James Webb Space Telescope, which
To test these new ideas, researchers are exploring the infant universe through simulations. “There’s actually been really remarkable progress since Webb launched, really in the last year or so, on numerical simulations,” Somerville told attendees, adding that these new simulations “perhaps are more appropriate and more informative for interpreting observations in the high-redshift universe.” As
NASA’s Neil Gehrels Swift Observatory captured an “orphan” black hole lighting up as it devoured a star on the outskirts of a distant galaxy. For starters, these phenomena are rare and none have ever been seen so far outside the core of a galaxy before. “We were looking for these star destruction events as a
Read this press release in Spanish here. How do black holes in the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances, which existed much earlier in the history of the universe. New research suggests that NASA’s Nancy Grace Roman
