In today’s paper, the authors use Cepheid distance moduli to study the structure of the SMC.
The authors of today’s paper created simulated galaxies, for which true properties are known. They then used synthetic observations to compare the true answers to the values observers would expect to recover.
Often science is a competition. Being first is sometimes important to get the well deserved credit for your work. Circumplanetary disks are currently a topic, in which you can still be first, since none has been detected so far. But is the current generation of telescopes already good enough to do that?
The exoplanet hunt is on. The stakes are high. What will our next-generation telescopes find?
A supernova goes off. A star has died. Can its partner have anything to do with it?
The Milky Way grew by accreting many smaller galaxies. What did these doomed galaxies leave behind, and what could they say about the Milky Way’s early past?
