What would happen if you took two galaxies and mixed them together over millions of years? A new image including data from NASA’s Chandra X-ray Observatory reveals the cosmic culinary outcome.
Astrophile is Joshua Sokol’s monthly column on curious cosmic objects, from the solar system to the far reaches of the multiverse
Astronomers have recently identified a peculiar bubble-like structure associated with an energetic pulsar known as PSR J1015−5719. The newly found feature, designated G283.1−0.59, is most likely a polar wind nebula. The findings were presented June 9 in a paper published on the arXiv pre-print server.
An unknown Mars-to-Earth-mass planet may lurk in the outer reaches of the Solar System.
An explanation of long-lived Saturn’s North Polar hexagonal circumpolar jet in terms of instability of the coupled system polar vortex – circumpolar jet is proposed in the framework of the rotating shallow water model, where scarcely known vertical structure of the Saturn’s atmosphere is averaged out.
Einstein’s greatest theory has aced another test. Two stars are speeding around the big black hole at the Milky Way’s core in just the way his general theory of relativity predicted.
By combining the power of a “natural lens” in space with the capability of NASA’s Hubble Space Telescope, astronomers made a surprising discovery—the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.
In April, NASA’s robotic probe Cassini attracted widespread media coverage as it neared the end of its expedition of Saturn and its moons. While NASA celebrates the remarkable success of Cassini, it is hard not to look towards the future and ask, ‘what’s next?’
