In 2007, a student discovered a really weird thing in archival radio data. David Narkevic was working for Duncan Lorimer and found a 5-millisecond burst of energy in the Radio that appeared to be of extragalactic origin. In the years since then, over 100 of these objects have been discovered, with a few of them repeating on a regular basis. No one had predicted something like this should exist, and figuring out what exactly we’re seeing has been a wild ride. And the ride has not yet reached the end. Based on what we’ve seen so far, the radio bursts are caused by high energy,...

Euclid releases first images
Just when we thought nothing could be more stunning than the images being released almost weekly by JWST, along comes the newest space telescope on the block - the European Space Agency’s Euclid. The mission launched in July of this year, and as with JWST, has...
New Simulation Provides More Accurate Model of Everything

“Perfect Pairs” of black holes may dot universe
Image Credit: APS/Alan Stonebraker Pairs of objects are responsible for some of the coolest phenomena in our universe, and while a lot of these pairs end up merging into a single object given enough time, there are a few… theoretically at least… that the universe...
Gamma Ray Burst reveals Tellurium
Image Credit: NASA, ESA, CSA, STScI, A. Levan (IMAPP, Warw), A. Pagan (STScI) One of the awesome things about growing older as an astronomer is you get to see the weird stuff no one understood in your youth become the everyday normal of your middle age. While we still...
Dark “Stars” or galaxies?
JWST initially identified these three objects (JADES-GS-z13-0, JADES-GS-z12-0 and JADES-GS-z11-0) as galaxies in December 2022. Now a team suggests they might be “dark stars,” theoretical objects powered by particles of dark matter annihilating. Credit: NASA/ESA We...
Found: Galaxies lining up in early universe
This deep galaxy field from Webb's Near-Infrared Camera shows an arrangement of 10 distant galaxies (white circles) in a diagonal. NASA, ESA, CSA, Feige Wang/University of Arizona and Joseph DePasquale/STScI Currently, a lot of the research we see coming from JWST is...
Found: Time slows with distance
Before we go to break, I want to highlight one more piece of news. In a new paper in the journal Nature Astronomy, researchers Geraint Lewis and Brendon Brewer show evidence for time appearing to tick slower in the early universe. According to relativity, as our...
