The study of astronomical transients—objects that brighten, fade, or appear suddenly—using survey telescopes and multi-wavelength follow-up observations.
MIT-led astronomers say ZTF J0440+2325, 300 light-years away, is the first system seen where one low-mass object steadily feeds on another. Nobody has settled how long the feeding can last, and published estimates run from hundreds of thousands to billions of years.

A Syracuse-led team says a star that arrives already rotating fast cannot be spun up much further, which lets each weaker pass finally look weaker. Four of about ten known repeaters fade.

NASA's Roman Space Telescope, launched Aug. 30, 2026, will find planets in the brief brightening of background stars. That method reaches the cold, wide orbits current catalogs barely sample.
Reality
Astronomers scheduled an X-ray observation to land on a predicted outburst of AT 2016blu and saw emission consistent with accretion onto a compact companion. It is the first luminous blue variable reported with such a partner.
Reality
Astronomers report helium moving unexpectedly fast long after AT2024wpp peaked, which they read as surviving stellar structure. That complicates the tidy version of tidal disruption.
