A team of astronomers has discovered a unique system of quadruple quasars. The quartet, discovered at the very edge of the universe, is one of the most massive structures in the known universe.
Highschool students analyzing data obtained with the 100-meter Robert C. Byrd Green Bank Telescope have discovered an exotic pulsar with the widest orbit known to date. Pulsars (pulsating radio stars) are some of the most spectacular things in the known Universe. They are basically highly magnetized, rotating neutron stars that emit beams of electromagnetic radiation. This radiation can be observed when the beam
Just after NASA researchers made the bold claim that they will find alien life in less than 20 years, the space agency has officially launched a project to look for it. The Nexus for Exoplanet System Science, or “NExSS” will be a project integrating several fields of science, aiming to better understand exoplanets with the potential to host life, as well as planet-life interactions.
NASA’s Dawn spacecraft already has an impressive resume – it’s traveled to the strange area between Mars and Jupiter and managed to start orbiting the dwarf planet Ceres, even though Ceres measures only 950 kilometers (590 miles) in diameter and has a very small gravitational field. But it’s not stopping just yet – after previously revealing a number of black and white pictures, Dawn has now provided a color photograph, but here’s the thing – it poses more questions than it answers.
Astronomers have known for quite a while that Mars has distinct polar ice caps, but the Red Planet might also have belts of glaciers at its central latitudes in both the southern and northern hemispheres. These huge glaciers are covered by a thick layer of dust which masks them and makes them seem like they are actually part of the surface of the ground.
When it comes to alien life, we’ve had our hopes crushed time and time again. As the Moon was being observed with telescopes in medieval times, many thought it might be inhabited, but then we learned there’s not atmosphere and no water on it. Then Venus, our sister planet turned out to be completely unsuitable for life, and even Mars seems to
A chance discovery has provided experimental evidence that stars may generate sound. While he was examining the interaction of an ultra-intense laser with a plasma target, John Parsley from the University of York found that interfering plasma generates a series of pressure pulses – in other words, sounds.
The Moon’s geologic past was much more interesting and active than previously thought, results from the Chinese lunar rover indicate. The Yutu moon rover found evidence of at least nine distinct rock layers deep beneath its wheels, something which seems to indicate a more complex setting.
At the core of a newly found dwarf galaxy, astronomers discovered a mysterious source of gamma rays that may signal the presence of the mysterious dark matter. If this is confirmed, then it would be the first time we see dark matter through anything else than its gravitational pull.
For the second time, astronomers have discovered a planet in a solar system with four stars! While most solar systems only have one star, two stars are pretty rare, three are very rare, and four stars… that almost never happens – or at least this is what we thought. The planet wasn’t newly discovered, but previously, astronomers thought it resides
