Pulsars - tiny spinning stars, heavier than the sun and smaller than a city - have puzzled scientists since they were discovered in 1967. Now, new observations by an international team make these bizarre stars even more puzzling.
A University of Alberta professor has revealed the workings of a celestial event involving binary stars that produce an explosion so powerful its luminosity ranks close to that of a supernova, an exploding star.
While studying a meteorite from Vesta, geoscientists found evidence that planet-like dynamic processes also occurred in the asteroid. Simulations by scientist Gregor Golabek from ETH Zurich confirmed this assumption.
In 1901 the star GK Persei gave off a powerful explosion that has not stopped growing and astonishing ever since. Now a team of Spanish and Estonian astronomers has reconstructed the journey of the emitted gas in 3D which, contrary to predictions, has hardly slowed down its speed of up to 1,000 km/s after all this time.
Michael Veto, a third-year graduate student in the School of Earth and Space Exploration (SESE) at Arizona State University, has been chosen to build an infrared and visible light camera system that will launch on a space satellite.
The National Space Society (NSS) has just launched a campaign on the popular Kickstarter internet platform for the creation of a cutting-edge film about the ways in which all of humanity benefits from the expansion of space exploration and development.
A NASA sounding rocket flight in 2012 captured five minutes of the highest-resolution images ever taken of the Sun's million-degree outer atmosphere, the corona. The new images have provided tantalizing hints of another mechanism that likely contributes to the heating of the solar corona.
A new image from the Atacama Pathfinder Experiment (APEX) telescope in Chile shows a beautiful view of clouds of cosmic dust in the region of Orion. While these dense interstellar clouds seem dark and obscured in visible-light observations, APEX's LABOCA camera can detect the heat glow of the dust and reveal the hiding places where new stars are being formed. But one of these dark clouds is not what it seems.
Inserting new capabilities into a satellite is no simple task. Doing so as that satellite hurdles through space 22,000 miles above the Earth is a bit more challenging. DARPA's Phoenix program, which hopes to repurpose retired satellites while they remain in orbit, seeks to fundamentally change how space systems could be designed here on earth and then sustained once in space.
Multiple arcs are revealed around Betelgeuse, the nearest red supergiant star to Earth, in this new image from ESA's Herschel space observatory. The star and its arc-shaped shields could collide with an intriguing dusty 'wall' in 5000 years.
