Tue, 21 Feb 2017 12:37:31 ESTA team led from the Instituto de Astrofísica de Canarias (IAC) has found the most precise way ever to measure the rate at which stars form in galaxies using their radio emission at 1-10 Gigahertz frequency range.
Tue, 21 Feb 2017 08:40:01 EST(Phys.org)—A pair of researchers with the Physical Research Laboratory in India studying data sent back from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) probe has found possible evidence of the development of rings around the planet. In their paper published in the journal Icarus, Jayesh Pabari and P. J. Bhalodi describe the data, what the probe has measured, and the likelihood that some of the dust that surrounds Mars may one day accumulate into a set of rings encircling the planet.
Tue, 21 Feb 2017 06:20:07 ESTOur 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 objects that are used to define the coordinates of all other sources.
Tue, 21 Feb 2017 05:17:28 ESTESA's XMM-Newton has found a pulsar – the spinning remains of a once-massive star – that is a thousand times brighter than previously thought possible.
Mon, 20 Feb 2017 12:41:30 ESTAstronomers 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.

Mon, 20 Feb 2017 09:07:55 EST(Phys.org)—A team of researchers from around the world is getting ready to create what might be the first image of a black hole. The project is the result of collaboration between teams manning radio receivers around the world and a team at MIT that will assemble the data from the other teams and hopefully create an image.
Mon, 20 Feb 2017 09:00:01 EST(Phys.org)—Astronomers have presented the results of new photometric and spectroscopic observations of the star V501 Aurigae (V501 Aur for short), providing new insights into the nature of this object. The findings show that V501 Aur, previously considered to be T-Tauri star, is most probably a field binary. The study was published Feb. 15 in a paper available on arXiv.org.
Mon, 20 Feb 2017 08:55:35 ESTOver the past decades, scientists have wrestled with a problem involving the Big Bang Theory. The Big Bang Theory suggests that there should be three times as much lithium as we can observe. Why is there such a discrepancy between prediction and observation?
Mon, 20 Feb 2017 08:50:03 ESTMike Fossum is a shining example for astronaut wannabes shooting for the stars. His story undeniably proves that dreams of space voyages come true if you have the motivation and courage to pursue them. In an interview with Astrowatch.net, the veteran NASA astronaut talks about his successful astronaut career, recollecting unforgettable and thrilling moments in space.

Mon, 20 Feb 2017 07:34:27 ESTWhen 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 different galactic populations.
