In the race to resolve the tension between cosmological and local measurements of the Hubble constant, another method enters the contest… using gravitational wave signals without an electromagnetic counterpart!!
What if JWST’s early massive galaxies are not overestimated, but underestimated? A bottom-heavy IMF could hide tons of mass in faint stars.
Whether you’re a six-year-old scouring the backyard on Easter morning, or an exoplanet astronomer with observing time on the James Webb Space Telescope, nothing beats the feeling of finding what you’re looking for. So, you can imagine the authors of today’s paper were pretty excited when they received their transmission spectroscopy data of the sub-Neptune known as TOI-270d.
There is a tradition in Astronomy to post silly science papers to the arXiv on Aprils Fools day. We’ve collected them all for 2026 and provided some “peer review”.
In today’s bite, the LHAASO collaboration tackle a gamma ray mystery in the LS I +61 303 system, investigating just who (or what) might be responsible.

Why do we see so many massive, dead galaxies at early cosmic times? Guest author Tatevik Mkrtchyan illuminates a slice of the cosmic graveyard!
