What if dark matter came in two states?

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...

Celestial wonders in Leo

Leo is a prominent sight for stargazers in April. Its famous sickle, punctuated by the bright star Regulus, draws many a beginning stargazer's eyes, inviting deeper looks into some of Leo's celestial delights, including a ...

First close pair of supermassive black holes detected

Supermassive black holes at the centers of galaxies are one of the most active fields of research in astronomy. In order to accumulate their enormous masses, they must merge with each other. A research team led by Silke Britzen ...

How Jupiter cultivated more large moons than Saturn

The two largest planets in our solar system, Jupiter and Saturn, also have the largest satellite systems, or the most moons. At present, Jupiter's reported moon count stands at more than 100 moons, and along with its many ...

'Hot Jupiter' orbiting a metal-poor star discovered

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new "hot Jupiter" exoplanet. The newfound alien world, designated TOI-7169 b, orbits a metal-poor star, which ...

Looking up? How to photograph the moon with your phone

Eyes are on the sky this week as four astronauts get the closest humans have been to the moon for more than 50 years on NASA's Artemis II mission. Join the millions of people looking up while it's on its way and we'll show ...

Two's company: Scientists identify new class of star remnants

In about 5 to 8 billion years, our sun is expected to evolve into a white dwarf—an extremely dense, Earth-sized stellar remnant that has exhausted its fuel and shed its outer layer. But while our sun is a solitary star, research ...

The most pristine star yet found in the known universe

An unusual team of astronomers used Sloan Digital Sky Survey-V (SDSS-V) data and observations on the Magellan telescopes at Carnegie Science's Las Campanas Observatory in Chile to discover the most pristine star in the known ...

The RCW 36 nebula: A cosmic hawk and its baby stars

This image, taken with ESO's Very Large Telescope (VLT), seems to have captured a cosmic hawk as it spans its wings. While the dark clouds in the middle of the image make up the head and body of the bird of prey, the filaments ...

HETDEX data reveal a vast 'sea of light' between early galaxies
