Death From Space — What Are Gamma-Ray Bursts

Death From Space — What Are Gamma-Ray Bursts

Imagine that you can get the energy from every star in a radius of 100 million light-years. Of thousands of galaxies, each of which has billions of stars. Try to imagine that you are capable of taking this kind of energy and using it in the greatest super weapon in the universe. The ruin you will cause is unimaginable.  In fact, you do not have to imagine it, because all of this already exists in the form of gamma rays. What are these “space snipers” that shoot the Universe at random intervals. What happens if they hit us? Another interesting...
Big Bang May Have Created a Mirror Universe Where Time Runs Backwards

Big Bang May Have Created a Mirror Universe Where Time Runs Backwards

Why does time seem to move forward? It’s a riddle that’s puzzled physicists for well over a century, and they’ve come up with numerous theories to explain time’s arrow. The latest, though, suggests that while time moves forward in our universe, it may run backwards in another, mirror universe that was created on the “other side” of the Big Bang. Two leading theories propose to explain the direction of time by way of the relatively uniform conditions of the Big Bang. At the very start, what is now the universe was homogeneously hot, so much so that matter didn’t really...
The Collision that Formed the Moon has Helped to formation of Life on Earth

The Collision that Formed the Moon has Helped to formation of Life on Earth

The process responsible for the formation of the Earth does not imply the existence of key ingredients for life. New research, however, shows how our planet probably has acquired them. Scientists are saying a Mars-sized planet has hit the Earth about 4.4 billion years ago. On the one hand, it served as a “donor” to the important ingredients for life, as its core was rich in sulfur. On the other – it has led to the formation of the Moon, our natural companion. Experiments prove that much of the nitrogen and carbon of the Earth is the result of this...
New NASA Animations Show How Slowly Light Travels Through Space

New NASA Animations Show How Slowly Light Travels Through Space

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second) If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Thanks to the work of Albert Einstein and others, we now understand light speed to be a theoretical limit: light speed — a constant called “c” — is thought to be not achievable by anything with mass. Is the speed of light really constant?Light travels in waves, and, like sound, can be slowed depending on what it is traveling through. Let’s Start A new...
Mysterious Radio Signals from Deep Space Detected

Mysterious Radio Signals from Deep Space Detected

Astronomers have revealed details of mysterious signals emanating from a distant galaxy captured by a telescope in Canada. The exact nature and origin of the radio waves are unknown, the BBC writes. Among the 13 fast radio bursts, there was also a very unusual repeating signal, coming from the same source at a distance of about 1.5 billion light-years. Such an event was reported only once before by another telescope. Ingrid Stears, an astrophysicist at the University of British Columbia, says, “Knowing that there was such a thing before, we supposed there were such things somewhere. With more repeaters and more...
Scientists Have Made a Detailed Map of the Milky Way

Scientists Have Made a Detailed Map of the Milky Way

An international team of astrophysicists has made one of the most detailed maps of the Milky Way far. They are united by the International Center for Radio Astronomy Research (ICRAR), which publishes the map and survey data. It shows the distribution of neutral atomic hydrogen in the galaxy. This is the element with the greatest abundance in the Universe and is essential for Galaxies and Stars. The HI4PI project has explored this through over a million individual observations and around 10 billion individual information points. Although hydrogen is abundant in the Universe, detecting it with sufficient detail for mapping has...
