"When beggars die, there are no comets seen;
The heavens themselves blaze forth the death of princes."

Luminous Fast Blue Optical Transients Are Likely Large Black Holes Shredding Their Massive Companions

Universe Today - Thu, 12/18/2025 - 1:14pm

In 2024, astronomers discovered the brightest Luminous Fast Blue Optical Transient (LFBOT) ever observed. LFBOTs are extremely bright flashes of blue light that shine for brief periods before fading away. New analysis of this record-breaking burst, which includes observations from the International Gemini Observatory, funded in part by the U.S. National Science Foundation, challenges all prior understanding of these rare explosive events.

The JWST Found A Jekyll-and-Hyde Galaxy In The Early Universe

Universe Today - Thu, 12/18/2025 - 12:53pm

In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big Bang – a cosmic Jekyll and Hyde that looks like any other galaxy when viewed in visible and even ultraviolet light but transforms into a cosmic beast when observed at infrared wavelengths. This object, dubbed Virgil, is forcing astronomers to reconsider their understanding of how supermassive black holes grew in the infant universe.

Using Bent Light to Map Complex Planetary Architectures

Universe Today - Thu, 12/18/2025 - 9:31am

With new technologies comes new discoveries. Or so Spider Man’s Uncle Ben might have said if he was an astronomer. Or a scientist more generally - but in astronomy that saying is more true than many other disciplines, as many discoveries are entirely dependent on the technology - the telescope, imager, or processing algorithm, used to collect data on them. A new piece of technology, the Nancy Grace Roman Space Telescope, is exciting scientists enough that they are even starting to predict what kind of discoveries it might make. One such type of discovery, described in a pre-print paper on arXiv by Vito Saggese of the Italian National Institute for Astrophysics and his co-authors on the Roman Galactic Exoplanet Survey Project Infrastructure Team, is the discovery of many more multiplantery exoplanet systems an astronomical phenomena Roman is well placed to detect - microlensing.
