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

Scientists discover ice in space isn't like water on Earth after all

Space.com - Wed, 07/09/2025 - 5:00pm
Scientists had assumed that the ice in space was purely amorphous, but new experiments show it can have a partly crystalline structure similar to ice on Earth.

Finding An Ocean On An Exoplanet Would Be Huge and the Habitable Worlds Observatory Could Do It

Universe Today - Wed, 07/09/2025 - 2:44pm

The search for habitable exoplanets boils down to the search for water. Exoplanet scientists lack the technological capability to detect surface water on exoplanets from great distances, so instead they can only search for planets in habitable zones where surface water is likely. But what if we could directly detect the surface water itself?

Finding PBHs Using The LSST Will Be A Statistical Challenge

Universe Today - Wed, 07/09/2025 - 2:44pm

With the recent first light milestone for the Vera Rubin observatory, it's only a matter of time before one of astronomy’s most long-awaited surveys begins. The Legacy Survey of Space and Time (LSST) is set to start on November 5th, and will scan the sky of billions of stars for at least ten years. One of the most important things it hopes to find is evidence (or lack thereof) of primordial black holes (PBHs), one of the primary candidates for dark matter. A new paper from researchers at Durham University and the University of New Mexico looks at the difficulties the LSST will have in finding those enigmatic objects, especially the statistical challenges, and how they might be overcome.

New Heat Sink Tested in Space Uses Melting Wax to Regulate Temperature

Universe Today - Wed, 07/09/2025 - 2:44pm

It's cold in space, but overheating is a bigger problem than low temperatures. That's because the only way to regulate a spacecraft's heat is through radiation, or slowing down its computing. Engineers have tested a new type of heat sink in space that contains a wax-based phase change material that melts within the normal operating temperature range of the electronics, absorbing heat and then helping to radiate it away. The heat sink was part of a CubeSat launched in August 2024.

Two Powerful Space Telescopes are Better Than One

When the JWST was being built, some labelled it as the Hubble's successor. In some ways it is, even though the Hubble is still performing important science observations. When the two telescopes team up, we get the best of both.

Could Bioplastics be the Solution to Living Beyond Earth?

Universe Today - Wed, 07/09/2025 - 2:44pm

An international team of scientists led by the Harvard School of Engineering and Applied Sciences (SEAS) proposed a new method for living beyond Earth. Their experiment demonstrated how bioplastic structures can be grown using algae, which would be rugged enough to survive the hostile Martian environment.
