Planets beyond our solar system can have magnetic fields similar to those closer to home, astronomers said Tuesday after observing extreme winds on scorching worlds known as “hot Jupiters.”

Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients associated with galactic centers last only days or weeks, the galaxy SDSS […]

Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult to detect. Research on neutrinos requires massive underground observatories far from potential confounders that drown out their weak signals. […]

The moon is not the only natural object traveling through space alongside Earth. Several small asteroids travel around the sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete a full orbit. Today, we know of eight such “quasi-moons” or quasi-satellites.

Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations from Einstein’s theory of general relativity and quantum mechanics. […]

A rush rescue mission to save a NASA space telescope remains grounded, this time because of a last-minute launch problem.

Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.

Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star’s habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75% of the planet’s surface, life is abundant. But what about the exoplanet’s […]
