Astronomers have stumbled on a black hole roughly 600,000 times more massive than the Sun in a dwarf galaxy next to the Milky Way, according to a new study to be published in The Astrophysical Journal. Researchers inferred the black hole’s presence from the trajectories of 21 hypervelocity stars zipping through the Milky Way’s outskirts, finding that […]

There is a supermassive black hole at the center of our galaxy. There is also a lot of other stuff there as well. Young stars, gas, dust, and stellar-mass black holes. It’s a happening place.It is also surrounded by a veil of interstellar gas and dust, which means we can’t observe the region in visible light. We can

 45 years after its launch, NASA’s Voyager 1 is still traveling beyond our Solar System. However, the veteran spacecraft is suddenly sending back unusual data that is baffling its engineers. While the probe is still operational, readouts from its attitude articulation and control system – AACS for short – do not appear to match the

Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing over time, according to new observations released Wednesday.If dark energy is in fact weakening, it would likely mean that science’s understanding of how the universe works will need to be rewritten. The new findings come from

The James Webb Space Telescope (JWST) has achieved groundbreaking discoveries in the field of exoplanet studies. In particular, it has made strides in the analysis of their atmospheres by studying light from the parent star as it travels through the gas surrounding the planets.JWST recently observed gas giant planets in the system HR 8799 and

How black holes grow to monstrous scales is one of astronomy’s prevailing enigmas. A new record-breaking dataset, which reveals 300 potential ‘missing link black holes’, could help to unravel it.Astronomers have used the Dark Energy Spectroscopic Instrument (DESI) to discover a treasure trove of black holes, many of which are rare “missing links” in the cosmic monsters’

 A newly discovered crescent of galaxies spanning 3.3 billion light-years is one of the world’s largest known structures, challenging some of astronomers’ most fundamental assumptions about the universe. The epic arrangement known as the Giant Arc is made up of galaxies, galaxy clusters, and a lot of gas and dust. It is located 9.2 billion
