The Incredible Shrinking Mercury is Active After All

Wow – Mercury is geologically active.

It’s small, it’s hot, and it’s shrinking. Surprising new NASA-funded research suggests that Mercury is contracting even today, joining Earth as a tectonically active planet.

Irregular dimming of a young stellar object investigated by astronomers

More irregular dimming. Another Tabbi’s Star?

New research conducted by a team of astronomers, led by Simone Scaringi of the Max Planck Institute for Extraterrestrial Physics in Germany, examines peculiar dimming of a newly found young stellar object designated EPIC 204278916. The study tries to explain the nature of these dipping events observed in the object’s light curve. The results were published Aug. 25 in a paper available on arXiv.org.

Philae found!

Looks like they found the Philae lander!

Less than a month before the end of the mission, Rosetta’s high-resolution camera has revealed the Philae lander wedged into a dark crack on Comet 67P/Churyumov–Gerasimenko.

Physics Confronts Its Heart of Darkness

What other theories are there to patch some emerging holes in the concept of Dark Matter?

Cracks are showing in the dominant explanation for dark matter. Is there anything more plausible to replace it?
