Astronomers peer inside the mysterious void of our Cosmos

There’s a lot we can learn by looking at all those voids making #space between galaxies – and now, for the first time, #astronomers have used a new method to peer inside these mysterious pockets of #nothingness. Voids in space are due to the expansion of the Universe – this results in a web of […]

This Giant Fireball Over Michigan Was Visible From Six States and Canada

The National Weather Service says that the most likely explanation for an object which sent out illumination and a sonic boom throughout southwest Michigan, five other states, and Canada on Tuesday night was the breakup of a meteor, WXYZ reported. The American Meteor Society collected at least 200 reports of the incident, which for around a second was so bright it lit parts of the Detroit region like it was daytime.

Newly Announced Super-Earth May Be The Closest Exoplanet Discovered Yet

Gliese15Ab is a newly discovered planet roughly five times the mass of Earth. Researchers aren't sure what the planet's atmosphere is like, and it's close enough to its parent star to heat it past the boiling point of water. But the most interesting thing about Gliese 15Ab isn't how close it is to its star. It's how close it is to us.

What Lit Up The Universe? Astronomers May Be On The Brink Of An Answer

Most scientists can see, hear, smell, touch or even taste their research. But astronomers can only study light – photons traveling billions of light-years across the cosmos before getting scooped up by an array of radio dishes or a single parabolic mirror orbiting the Earth.

How Will Humans Get to Alpha Centauri?

Astronomers have discovered an Earth-sized exoplanet orbiting a star in Alpha Centauri, just 4.3 light-years from Earth. With surface temperatures in excess of 2,000 degrees fahrenheit, this particular planet would be inhospitable, but the fact that it exists at all raises hopes of finding another, more human-friendly planet within the same star system.
