Mosaic images from the COSMOS-Web program offer a treasure trove of early galaxies, including dazzling examples of spiral galaxies, gravitational lensing, and evidence of galaxy mergers.
The first detection of gravitational lensing for a single, isolated star other than our sun comes 100 years after a landmark experiment using the sun to confirm Einstein’s prediction
A new study indicates that scientists have substantially underestimated the energy output of active galactic nuclei powered by supermassive black holes because their light is dimmed by dust
Astronomers announced they may have finally defined the Milky Way’s farthest frontier
A search for variable stars called RR Lyrae has found some of the most distant stars in the Milky Way’s halo a million light years away.
Spectroscopic observations with JWST confirm four early galaxies dating back to less than 400 million years after the Big Bang, three of which are the most distant confirmed to date
A ‘mystery molecule’ seen in the initial spectrum has been identified as sulfur dioxide produced by photochemical reactions in the planet’s atmosphere
The James Webb Space Telescope is the largest and most powerful telescope humans have sent to space and, Batalha asserts, it is ushering in a new era of exoplanet science
Initial findings from JWST Early Release Science programs include the discovery of two exceptionally bright galaxies in the early universe
By studying intermediate-mass black holes, scientists hope to improve their understanding of the growth of supermassive black holes in massive galaxies
Bunnett Symposium 2023 This annual event was established in 2001 to honor and celebrate the late Prof. Joseph Bunnett’s seminal contributions: Prof. Bunnett was a pioneer in his sub-discipline of physical organic chemistry and a founding member of our department. The Bunnett Symposium has evolved into an opportunity to connect past and present friends of the Department for […]
Two researchers have won an NSF grant that will allow them to pursue the emerging technology of spectrometers on a chip – tiny devices for separating and measuring light at ultraviolet, visible, and infrared wavelengths which can enable advances in astronomy when used as part of telescope instrumentation.
