NASA, ESA, CSA release historic first images from the James Webb Space Telescope
NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) have released the first set of full-color images taken by the James Webb Space Telescope — the world’s newest, most powerful, and largest space telescope. A total of five images were released, with the first image being unveiled by United States President Joe…

Researchers use Hubble to observe dead star destroying planetary system
A team of researchers using archival data from the Hubble Space Telescope, a joint venture between NASA and the European Space Agency (ESA), as well as other NASA observatories have observed a white dwarf consuming and destroying a planetary system — the first time an observation of such kind has been made. The white dwarf, a…

James Webb targets detailed as commissioning nears completion
Over the past five months, the James Webb Space Telescope and the joint NASA, European Space Agency, and Canadian Space Agency teams behind the project have been working towards the completion of the observatory’s six-month-long commissioning phase at the Sun-Earth Lagrange point 2 (L2). With the observatory’s mirrors recently completing alignment, Webb and its teams…

New research directly observes atmospheric loss on mini-Neptune exoplanets, provides insight into exoplanet evolution
In two studies recently released by a group of astronomers researching exoplanets, the first direct observations of atmospheric loss on mini-Neptune exoplanets were confirmed. What’s more, the data from the studies points to the atmospheric loss potentially causing the mini-Neptunes to transform into super-Earth exoplanets — a stunning discovery in exoplanet research. “Most astronomers suspected…

New research from ESA’s CHEOPS observatory reveals rugby ball shape of strange exoplanet
Exoplanets all over the universe come in different sizes, compositions, colors, and temperatures. However, they typically don’t come in different shapes, as nearly every single planet ever discovered is thought to be spherical in shape — except for one. New data from the European Space Agency’s (ESA) Characterising Exoplanets Satellite (CHEOPS) space observatory, as well…

IXPE X-ray observatory completes commissioning, eyes Cassiopeia A for calibration
The pioneering Imaging X-ray Polarimeter Explorer (IXPE) telescope, the first observatory in space to perform detailed polarimetry of some of the highest-energy objects the universe has to offer, has ended its highly-successful commissioning phase just over 30 days after lifting off from the Kennedy Space Center on December 9, 2021, on a SpaceX Falcon 9…

Seeing the universe in the Mid-Infrared with James Webb’s MIRI instrument
The James Webb Space Telescope (JWST), presently tracking toward a launch no earlier than December 22 on an Ariane 5 rocket from the Guiana Space Centre in South America, will revolutionize in-space astronomy, particularly with its Mid-InfraRed Instrument, or MIRI. The instrument itself requires special cooling to drop its temperature to just 6 Kelvin —…

New research finds first clear detection of circumplanetary disk surrounding an exoplanet
In recently published research using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers announced that they had found the first clear detection of a circumplanetary, moon-forming disk surrounding the exoplanet PDS 70c — a first in astrophysics. The circumplanetary disk, or CPD, has been seen in past research from other groups. However, due to the inability…

With Hubble, astronomers use UV light for first time to measure a still-forming planet’s growth rate
In 2018, the exo-planet PDS 70b was observed using the Very Large Array. It’s discovery instantly placed it at the top of observation requests and telescope time for one quite profound reason: the exoplanet was still forming. For the first time, a still-accreting planet had been discovered, providing astrophysicists a unique opportunity to study how…
