A new test proves how to make the Event Horizon Telescope even better
Want a clear view of a supermassive black hole's environment? It's an incredible observational challenge. The extreme gravity bends light as it passes through and blurs the details of the event horizon, the region closest to the black hole. Astronome.....»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
Q&A: Astronomers await a once-in-80-year stellar explosion
We sat down with Carnegie Science Observatories theoretical astrophysicist Tony Prio to talk about T Coronae Borealis, the stellar explosion that occurs once every 80 years and is due to light up in the coming months......»»
Double-peaked supernovae offer clues to pre-supernova outbursts
New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
85% of the matter in the universe is missing: But scientists are getting closer to finding it
Most of the matter in the universe is missing. Scientists believe around 85% of the matter in the cosmos is made of invisible dark matter, which has only been detected indirectly by its gravitational effects on its surroundings......»»
Hubble zooms into the rosy tendrils of Andromeda
Clusters of stars set the interstellar medium ablaze in the Andromeda galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way's closest major galaxy. It measures approximately 152,000 light-years across and, with almo.....»»
