Ever since our species discovered the existence of other planets beyond Earth, the question of whether we are alone in this universe has intrigued scientists and philosophers.
One of the consistently difficult hurdles for space exploration is cost. With dwindling governmental support the initiative has moved toward the private sector.
For years, scientists have believed that black holes are a portal to no-return. Astronauts in movies fear the mouths of black holes because the nothingness extends into an unknown forever. Black holes have been known as Bermuda Triangles of space – what goes in is lost forever. Or so we thought.
Underneath some nondescript farmland near Geneva, on the border of France and Switzerland, the world’s biggest and most expensive scientific experiment is ready to re-start. LHC at the Cern laboratory – were preparing to switch it on today for the first time in two years, ahead of the next series of experiments.
Climbing up Mt. Sharp in the middle of Gale Crater, NASA’s Curiosity rover has discovered two-tone mineral veins on a layered mountain which provides new clues of multiple fluid movement episodes on Mars, including some that occurred later than the wet conditions that formed after lake-bed deposits at its base.
The universe has a lot of powerful and amazing stuff going on. One such thing is called fast radio burst or FRB. These radio signals are extremely fast, lasting about a millisecond and giving off as much energy as the sun does in a day.
Quasars are known to be super-energetic and compact regions surrounding a supermassive black hole at the center of a galaxy. Quasars usually get their luminosity and electromagnetic energy from the nearby black holes that spew back tons of energy in various forms while they feed on the mass from their surroundings.
Treasure seekers have found the haul of a lifetime, but it wasn’t in some ancient temple or mysterious island. Instead, it was in the sky.
Here on Earth, we take gravity so for granted that it took an apple falling from a tree to trigger Isaac Newton’s theory of gravitation. But gravity, which draws objects together in proportion to their mass, is about much more than fallen fruit. Read on for some of the strangest facts about this universal force.
