Webb researchers discover lensed supernova, confirm Hubble tension
Measuring the Hubble constant, the rate at which the universe is expanding, is an active area of research among astronomers around the world who analyze data from both ground- and space- based observatories. NASA's James Webb Space Telescope has alre.....»»
Scientists discover planet orbiting closest single star to our sun
Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered an exoplanet orbiting Barnard's star, the closest single star to our sun. On this newly discovered exoplanet, which has at least half the mass of.....»»
Webb detects fast outflow in the host galaxy of a luminous quasar
An international team of astronomers has employed the James Webb Space Telescope (JWST) to perform spectroscopic observations of a luminous quasar known as J1007+2115. They detected a fast outflow originating from the quasar's host galaxy. The findin.....»»
Observations explore the nature of transitional millisecond pulsar PSR J1023+0038
Using the Gran Telescopio Canarias (GTC), astronomers from Italy and Spain have carried out high-temporal-resolution optical spectroscopic observations of a transitional millisecond pulsar designated PSR J1023+0038. Results of the observational campa.....»»
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»
Black hole jet appears to boost rate of nova explosions

Hubble finds that a black hole beam promotes stellar eruptions
In a surprise finding, astronomers using the NASA/ESA Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called.....»»
‘That’s weird’: This galaxy could help astronomers understand the earliest stars
Astronomers using the James Webb Space Telescope have spotted a weird galaxy that originated just a billion years after the Big Bang......»»
Astronomers catch a glimpse of a uniquely inflated and asymmetric exoplanet
An international group of researchers including University of Arizona astronomers, using NASA's James Webb Space Telescope, has observed the atmosphere of a hot and uniquely inflated exoplanet. The exoplanet, which is the size of Jupiter but only a t.....»»
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic spectrum (from ex.....»»
New millisecond pulsar discovered
Using the Green Bank Telescope (GBT), astronomers have observed a globular cluster known as Terzan 6. They detected a new millisecond pulsar that is likely associated with this cluster. The finding was reported in a research paper published September.....»»
X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
NASA"s Chandra finds galaxy cluster that crosses the streams
Astronomers using NASA's Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure......»»
