More JWST observations are finding fewer early massive galaxies

There's a common pattern in science. We develop some new process or tool that allows us to gather all kinds of data we've never had before, the data threatens to overturn all we've assumed about some long-established theory, ...

Starlinks are easily detected by radio telescopes

Radio astronomy and satellite communication have a long common history. Advances made in one field have benefitted the other, and our modern era of spacecraft and mobile internet is a product of this partnership. But there ...

Hubble views NGC 4654 in the constellation Virgo

It's easy to get swept up in the swirling starry arms of this intermediate spiral galaxy, NGC 4654, in the constellation Virgo. The galaxy has a bright center and is labeled "intermediate" because it has characteristics of ...

Dynamical dark energy might explain strange 21-cm signal

Dark energy may evolve in time, and it may even connect through a new force of nature with dark matter. A researcher believes that we may have already seen evidence for this. Their findings have been reported on the preprint ...

Were galaxies much different in the early universe?

An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn"—the era after the Big Bang when stars first ignited and galaxies began to bloom.
