New Hubble data shows definitive evidence of a dwarf galaxy merging with the young Milky Way in the earliest phases of its evolution.
Observing across the starry “plains” of space, NASA’s James Webb Space Telescope has taken new images of NGC 2392, nicknamed the Lion Nebula. NASA’s Hubble Space Telescope previously viewed this planetary nebula in 2000, imaging the lion face-shaped target in visible light and revealing features such as the “mane” of hazy, comet-shaped objects. Now Webb […]
On July 27, technicians at NASA’s Kennedy Space Center in Florida installed a memory card containing 1,350,144 names as part of a commemorative plaque on the Nancy Grace Roman Space Telescope. The names were submitted by people globally, including astronauts from Artemis II and Artemis III. The memory card will travel with the Roman observatory […]
Since their discovery by NASA’s James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has been a puzzling scientific endeavor. One popular theory is that little red dots are supermassive black holes known as active […]
NASA’s Neil Gehrels Swift Observatory captured an “orphan” black hole lighting up as it devoured a star on the outskirts of a faraway galaxy. These phenomena are rare to begin with, and none had ever before been seen so far outside of a galaxy’s core. “We were looking for these star-shredding events as a way […]
NASA’s Hubble finds that star formation in the Andromeda galaxy has undergone a 500-million-year decline.
This Hubble image features spiral galaxy NGC 4654, located 72 million light-years away in the constellation Virgo (the Maiden).
Astronomers using NASA’s James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in our Milky Way galaxy. The young, nearby star Beta Pictoris was already known to host two giant planets: Beta Pictoris b, one of the first […]
Lee esta nota de prensa en español aquí. How do black holes at the center of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances, which existed much earlier in the universe’s history. New research suggests NASA’s Nancy Grace Roman Space Telescope, which […]
For the first time, scientists have used NASA’s IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. The results provide new insight into the structure of some of the most extreme objects in the cosmos, as NASA […]
