Globular clusters have far fewer binary stars than the solar neighborhood. New research identifies black hole burning as the ...

A new catalog of giant pulses from the Crab Nebula pulsar reveals a feature predicted to exist but not seen until now.

The jet-like appearance arises when this arrangement is viewed from the side; the team created synthetic images of their simulated spicules that show individual jet-like features. These “jets” have ...

This apparent paradox comes from the different nature of cold and warm clouds. Cold clouds are denser and more compact, occupying much smaller physical scales than warm clouds. So to match the length ...

Last year, gravitational wave detectors triggered on what may have been a collision involving a sub-solar-mass neutron star. New research investigates a potential link between this event and a ...

Figure 1: The Bullet Cluster, colour coded based on the strong and weak lensing–based mass reconstruction (blue/JWST), X-ray intensity (pink/Chandra), and radio intensity (green/MeerKAT) using three ...

In 2023, researchers reported the discovery of a bizarre white dwarf: one with a surface composed of hydrogen on one side and helium on the other. A handful of other white dwarfs with split or patchy ...

Redshift distribution: The median redshift for this sample is z = 3.3, which is higher than that of less luminous galaxies, suggesting that brighter submillimeter galaxies are found at higher ...

Getting these spacecraft to their destination will be a challenge The thriftiest path to get to Uranus, a trajectory called a Hohmann transfer that’s been used for other missions aimed elsewhere in ...

The IMF is important in many areas of astronomy, and it’s relied on especially heavily in studies of distant galaxies. The light from these galaxies is dominated by high-mass stars, with the emission ...

The authors find that the mass of the galaxy is 0.21 x 10 12 solar masses, the circular velocity of the galaxy at the maximum radius they look at (21.1 kpc) is 206 km/s, and the virial radius is 1.28 ...
