4.4 Billion Years Ago, a Planet Collided with Earth—And Changed Everything

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole's event horizon, where no light can escape the massive object's gravitational grip. The black hole's powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as the stars skim by the black hole. Credit: NASA, ESA, and D.

A mysterious isotope shift in ytterbium led scientists on a journey of discovery, revealing secrets about the structure of atomic nuclei. While hopes of a new dark force remain unproven, the findings provide crucial clues about the fundamental nature of matter and neutron stars.

This artist’s concept visualizes a super-Neptune world orbiting a low-mass star near the center of our Milky Way galaxy. Scientists recently discovered such a system that may break the current record for fastest exoplanet system, traveling at least 1.2 million miles per hour, or 540 kilometers per second.

Discover the Fiery Beauty of NGC 2040—A Star Cluster in Cosmic Bloom

February 16, 2025

This is an 80-million-pixel picture of the star cluster RCW 38, located 5500 light-years away in the constellation Vela. RCW 38 is a young cluster containing about 2000 stars, and is bursting with star-forming activity. The picture was taken with ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA), operating in Chile's Atacama Desert. It shows a mixture of gas, dust and stars, creating an extravagant, yet spectacular landscape. As VISTA observes infrared light, it is able to peer through most of the dust in this region, which would block our view when observing in visible light. Behind the dust, VISTA is showing young stars within dusty cocoons and cold 'failed' stars known as brown dwarfs, thus revealing the secrets within these young stellar nurseries.

In commemoration of Edwin Hubble's discovery of a Cepheid variable class star, called V1, in the neighboring Andromeda galaxy 100 years ago, astronomers partnered with the American Association of Variable Star Observers (AAVSO) to study the star. AAVSO observers followed V1 for six months, producing a plot, or light curve, of the rhythmic rise and fall of the star's light. Based on this data, the Hubble Space Telescope was scheduled to capture the star at its dimmest and brightest light. Edwin Hubble's observations of V1 became the critical first step in uncovering a larger, grander universe than some astronomers imagined at the time. Once dismissed as a nearby "spiral nebula" measurements of Andromeda with its embedded Cepheid star served as a stellar milepost marker. It definitively showed that Andromeda was far outside of our Milky Way. Edwin Hubble went on to measure the distances to many galaxies beyond the Milky Way by finding Cepheid variables within those levels. The velocities of those galaxies, in turn, allowed him to determine that the universe is expanding. Credit: NASA, ESA, Hubble Heritage Project (STScI, AURA)
