Weather forecast for the HWO: Cloudy with a chance of biosignatures
In today’s paper, we take a look at how pesky clouds might actually be a good thing when it comes to detecting biosignatures in exoplanet atmospheres with NASA proposed next generation space telescope, the Habitable Worlds Observatory.
First Observations of γ-rays from the Solar Halo
The Sun doesn’t just shine—it also shapes the high-energy γ-ray sky by interacting with cosmic rays. Using 15 years of Fermi-LAT data, researchers detected the solar γ-ray halo in unprecedented detail and linked it to the same cosmic ray electrons measured near Earth. This study reveals how γ-ray observations can uncover the invisible influence of the Sun’s magnetic field across the heliosphere.
Planetary Hide and Seek
Are there planets inside the gaps of multi-planetary systems hiding from us?
Let’s Ce(rium) What’s Up With Mass Transfer!
Stars in binaries can have very unusual evolutionary paths, which can also affect their chemistry! Today’s paper takes a look at one such peculiarity: Mass transfer, and it’s resultant heavy element enhancement.
Running on empty: satellite galaxies lose their fuel easily
Today’s bite explores how a satellite galaxy can lose its fuel through ram pressure stripping when it falls into the orbit of a galaxy like the Milky Way.
Uncovering Precession for GW190521: How the Last Cycle Cracked the Case
Hidden in the final moments of the gravitational wave signal, a tiny detail holds powerful clues about how these massive black holes spiraled into each other and merged.
