This Antarctic glacier retreated, then totally collapsed

(Professor Anna Hogg)

Using satellite images and in-situ oceanographic measurements to track Cadman Glacier for more than three decades, a team of scientists has reported a dramatic glacial retreat of 5 miles (8 kilometers).

Dark matter may be hiding in the LHC's particle jets

(CERN/Claudia Marcelloni/Max Brice)

A new search for dark matter has turned up empty handed - but, in a silver lining, the effort provided important limits that will help future experiments narrow down the hunt for this elusive substance.

Data science helps cross-check space discoveries

(NASA, ESA, CSA, STScI, Webb ERO Production Team)

Matching astronomical objects is critical for space scientists because different surveys supply different information, whether that be wavelength data, exposure times, or even the date the survey was done. With so much data, it is often hard to match objects to one another across surveys. That's why one group at Johns Hopkins University turned to data science to develop a new method of making such matches.

'Haze' makes it harder to identify water on alien worlds

(Roberto Molar Candanosa/Johns Hopkins University)

One of the primary tasks of the James Webb Space Telescope (JWST) is to scan the atmospheres of exoplanets for signs of habitability. And, as far as we know, water is necessary for life. So naturally, detecting the presence of water in and around alien worlds is a high priority for planetary scientists. There is, however, one problem.
