When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it appears? Or does the star merely look reddish, since its light has had to travel through a cloud of ...
The U.S. Naval Research Laboratory (NRL), in partnership with NASA's Marshall Space Flight Center (MSFC), has developed StarBurst, a small satellite (SmallSat) instrument for NASA's StarBurst Multimessenger Pioneer mission, ...
Blazars are active galaxies that emit narrow jets of ionized matter from their centers, aimed towards Earth. Depending on properties of the electromagnetic radiation emitted by the jets, astronomers divide such objects into ...
An international team of astronomers working with the Canada France Hawaii Telescope have discovered a whopping 128 more moons orbiting Saturn. The Minor Planet Center confirmed the discoveries on March 11. The team observed ...
There is a supermassive black hole at the center of nearly every big galaxy—including ours, the Milky Way (it's called Sagittarius A*). Supermassive black holes are the densest objects in the universe, with masses reaching ...
In the past three years, astronomers have discovered a mysterious new type of radio source. We call these long-period transients.
On 12 March 2025, ESA's Hera spacecraft for planetary defense performs a flyby of Mars. The gravity of the red planet shifts the spacecraft's trajectory towards the Didymos binary asteroid system, shortening its trip by months ...
An international team of astronomers led by scientists from the Netherlands has shown that a white dwarf and a red dwarf orbiting each other every two hours are emitting radio pulses. Thanks to observations with several telescopes, ...
A discovery made by a team led by researchers at the University of Michigan tugs at the seams of some key cosmic lessons we thought we had learned from our own galaxy.
In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly magnetized rapidly rotating, light-emitting neutron star) and a so-called companion star. The companion ...
