Radio astronomy has a pollution problem. Satellites thousands of kilometres overhead, designed to broadcast communications or relay data, are increasingly contaminating the frequencies astronomers use to study the universe. While much attention has focused on SpaceX's Starlink and other low Earth orbit constellations, but what about the satellites much farther away?

Hubble Catches Another Glimpse of 3I/ATLAS
On July 1st, 2025, the third interstellar object (ISO) ever detected was seen making its way through our Solar System. Shortly after being alerted by automated detection systems, astronomers at the European Space Agency (ESA) began using observatories in Hawaii, Chile, and Australia to get a better look at the interstellar interloper. Since then, 3I/ATLAS has been observed by multiple space observatories, including the venerable NASA/ESA Hubble Space Telescope. On Nov. 30th, Hubble viewed the ISO again, which is about to make its closest approach to Earth.
Study: Current, future megaconstellations risk space-based astronomy

One of the biggest impacts to the low Earth orbit environment in the near-term and long-term future are satellite megaconstellations, according to a new study, published in the journal Nature. Companies, like Amazon, OneWeb and SpaceX, along with governments, like China and the United States are keen on the idea of controlling hundreds, thousands or even tens of thousands of satellites that serve a connected purpose.

The Search for Life Tops NASA's Science Goals for the First Human Mars Mission
When astronauts finally set foot on Mars, they'll arrive carrying the weight of centuries of speculation about whether life exists beyond Earth. Now a new report from the National Academies has settled a fundamental question about priorities: searching for evidence of past or present Martian life should be the primary science objective for humanity's first crewed mission to the red planet, ranking above all other scientific goals including understanding the effects of Mars on human health.
