The Paranal solar ESPRESSO Telescope (PoET), installed at the European Southern Observatory’s (ESO’s) Paranal site in Chile, has made its first observations. The telescope will work with ESO’s ESPRESSO instrument to study the sun in […]

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 […]

Fast solar winds originating from the sun can have direct impacts on Earth—disrupting systems like GPS, aviation, electrical grids, and satellite and radio communications. A new paper by New Mexico State University astronomy graduate student […]

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 […]

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 […]

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 […]

By analyzing the data from the Pan-Andromeda Archaeological Survey (PandAS), European astronomers have discovered a new satellite of the Andromeda galaxy. The newfound object, which received the designation Andromeda XXXVI, appears to be an ultra-faint […]

The Eberly Telescope Dark Energy Experiment (HETDEX) has discovered tens of thousands of gigantic hydrogen gas halos, called “Lyman-alpha nebulae,” surrounding galaxies 10 billion to 12 billion years ago. Known as Cosmic Noon, this is […]

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 is rare among exoplanets. […]

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 […]
