Where starlight doesn’t reach, new things are born: For the first time, an international research team has directly measured the effect of cosmic radiation in a cold molecular cloud. The observation shows how charged high-energy […]

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe […]

Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. The discovery was detailed in […]

Europe’s ESO star-gazing organization on Monday welcomed plans to call off building a massive green energy project in the Chilean desert which threatened to spoil its telescopes’ view of the darkest skies on Earth.This post […]

This NASA/ESA Hubble Space Telescope image features an uncommon galaxy with a striking appearance. NGC 7722 is a lenticular galaxy located about 187 million light-years away in the constellation Pegasus.This post was originally published on […]

Most near-Earth asteroids are thought to drift in from the main asteroid belt. But a small subset may have a much closer origin: the moon. One intriguing example is 469219 Kamoʻoalewa (2016 HO3), an Earth […]

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet transiting a distant star. The newfound alien world, designated TOI-6692 b, is the size of Jupiter and […]

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose that perhaps gravity itself […]

A Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of […]

Deep in the frozen heart of Antarctica, the South Pole Telescope has been watching one of the most extreme neighborhoods in our galaxy, and it’s just caught something extraordinary happening there. Astronomers have detected powerful […]
