- Scientists have identified a neutron star that is consuming material so fast it emits more x-rays than any other. Its extreme brightness can only be explained if the star has a complex multipolar magnetic field, the researchers say.
- NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.
- "The Curiosity of Martian Mud Cracks"
Afternoon Astronomy Coffee Hangout
NASA's Curiosity rover certainly has uncovered unusual features of Mars. Recently the rover was used by scientists to take a closer look at grid-like patterns of shallow ridges on slabs of rock. It seems that these ridges may have originated as cracks in drying mud, similar to features seen in drying lake beds on Earth. If it turns out that these are indeed mud cracks, they show that the generally wet conditions long ago a
- Astronomers will be taking over Austin, Texas, 4-8 June for the 230th AAS meeting. If you want to be a part of it and share your work with your colleagues from around the country, submit your oral presentation or poster abstract in one of over 50 topical categories by Thursday, 2 March, at 9:00 pm ET. If you don't think you'll be ready by 2 March, the late abstract deadline is 19 April. Only poster abstracts may be submitted after 2 March and those posters will be displayed on Thursday, 8 June.
- The next meeting in the AAS Topical Conference Series (AASTCS) is on Radio Exploration of Planetary Habitability and will take place 7-12 May 2017 in Palm Springs, California.
The idea of this meeting grew out of the need to better understand star-planet interaction and its impact on habitability of planetary companions, especially those in close orbits around low-mass stars. The meeting will address a wide range of related topics, broadly divided into three categories:
Stellar activity and pla

- Air Force Col. Thatcher Cardon won the agency's "Space Poop Challenge," an effort to design better ways for astronauts to deal with bodily waste than the current super-absorbent diapers.
- Our galaxy's gravitational field limits the accuracy of astrometric observations of distant objects. This is most apparent for objects that are obscured behind the central regions of the galaxy and the galactic plane, where the deviation can be up to several dozen microarcseconds. And more importantly, the effect of this gravitational "noise" cannot be removed. This means that beyond a certain point, it will no longer be possible to improve the accuracy of determining the position of reference o

- Astronomers are borrowing principles applied in biology and archaeology to build a family tree of the stars in the galaxy. By studying chemical signatures found in the stars, they are piecing together these evolutionary trees looking at how the stars formed and how they are connected to each other. The signatures act as a proxy for DNA sequences. It's akin to chemical tagging of stars and forms the basis of a discipline astronomers refer to as Galactic archaeology.

- When a star like our sun gets to be very old, after another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining, it will shrink to a fraction of its radius and become a white dwarf star. White dwarfs are common, the most famous one being the companion to the brightest star in the sky, Sirius. As remnants of some of the oldest stars in the galaxy, white dwarfs offer an independent means of dating the lifetimes of dif

The central galaxies in big clusters are thought to be bereft of stellar nurseries. They’re bathed in hot, X-ray-emitting gas, too superheated to form cool, star-forming clouds. The likely thermostat regulator in this setup is the galaxy’s gas-gobbling central black hole, which blasts out jets and radiation like a tempestuous radiato
