The Kepler Mission has measured planet radii and orbital periods for 3,000+ light curves. So what is next? Either we convince the continental USA to become amateur astronomers… Or we figure out ways to retrieve more planetary parameters from the Kepler data set. I’ll stick with the later. And so will the authors or this paper.
Distance is a tricky thing to measure in astronomy. We can’t use tape measures or rulers, and even more sophisticated methods like laser ranging are only good for the very nearest of neighbors, like the moon. That’s where distance indicators like Cepheids come in.
The space between galaxies, long thought to be a near empty void, is now rapidly being revealed to be home to a host of astronomical phenomena. Now astronomers may have added a new type of intergalactic resident to the list: a super-massive black hole, a million times the mass of the Sun, kicked out from its home galaxy.
The El Gordo (in Spanish, “the fat one”), one of the most massive galaxy clusters observed, is an active merger of two large subclusters. Unraveling its dynamics provides insights into $latex \Lambda$CDM.
The recent discovery of two pulsating, compact stellar remnants intertwined in a binary system has uncovered a system never-before observed in our Universe, and will offer new avenues for studying the exotic objects involved.
Water is essential for life, but where does it come from? Read on and learn that a significant amount is inherited from the interstellar medium.
Sometimes stellar remnants cannibalize other stars, emitting x-rays that can be detected in distant galaxies. Learn how making a careful tally of these gruesome events can reveal how stars are formed.
Habitable zone estimations take the climate regulation of the carbon cycle into account. But are we drawing the edges of the habitable zone too wide?
If you didn’t know already, asteroseismology is awesome. Read on to hear why…
Only the combined effort of observational and theoretical methods can really bring us to a more thorough understanding of the Universe throughout all spatial scales. The authors of today’s paper use and adapt the moving-mesh fluid mechanics code AREPO to function with protoplanetary disks and test its imprint on the potential of planets to open up gaps in the surrounding gas.
