It’s a well-known fact that Earth’s ozone layer protects us from a great deal of the Sun’s ultra-violet radiation. Were it not for this protective barrier around our planet, chances are our surface would be similar to the rugged and lifeless landscape we observe on Mars.
Space is an absolutely crazy place. Most science fiction writers throw in a planet with two stars that looks vaguely like Southern California, and call it a day. But the cosmos is a lot stranger than we give it credit for.
The universe is vast, making it extremely difficult to measure distances between heavenly bodies. Currently, the most common method can measure relative distances, but researchers from the Niels Bohr Institute at the University of Copenhagen, the University of Southampton, and the Kyoto Sangyo University have found another way thanks to “Eye of Sauron.”
In the recent past, a lot of unusual features are rportedly being noticed in Mars. The latest to join the numerous other things that have been allegedly found is an alien skull that looked like it was buried in Martian sand.
Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations from the Hubble Space Telescope challenge a previous theory for the apparent disappearance of a massive number of stars.
Christopher Nolan’s Interstellar raises a few questions about the possibility of wormhole travel. If Earth were to ever come to shambles, would the solution be to teleport to another planet via a double-ended tunnel – essentially a short cut though space?
2005 cassini captures an astonishing sight, a hundred geysers shooting ice particles miles into space from cracks in the south pole. Enceladus is hurdling its guts into space at a colossal rate. As enceladus orbits saturn, these icy plumes feed a vast shimmering halo around the planet the mysterious e ring.
When a star dies in a violent, fiery death, it spews its innards out across the sky, creating an expanding wave of gas and dust known as a supernova nebula. Arguably, the most famous of these supernova remnants is M1, also called the Crab Nebula, a blob-like patch visible in low-powered binoculars.
Quasars are the most luminous objects in the universe, beacons that shine across vast cosmological distances. They are galaxies that have particularly active supermassive black holes at their cores, objects surrounded by discs of extremely hot matter spiralling into oblivion and emitting bright beams of particles along their spin axes at nearly the speed of light.
Understanding the magnetic fields of planets is important for understanding how they interact with the rest of the cosmic bodies around them. Now, scientists have developed a new method that allows them to estimate the magnetic field of a distant exoplanet, telling them a bit more about the planet outside of the solar system.
Astrobiologists like to argue about the various parameters required for planetary habitability, but one thing they tend to agree on is that water must be present. A new theory upends this assumption by suggesting that alien life could thrive on “supercritical carbon dioxide” instead.
