A Key to the Search for Alien Life? –“Earth’s Atmosphere has a Nitrogen Signature That’s Unique to Our Planet”




A team of scientists reports the discovery of a planetary-scale "tug-of-war" of life, deep Earth and the upper atmosphere that is expressed in atmospheric nitrogen. Compared with other key elements of life — such as oxygen, hydrogen and carbon — molecular nitrogen is very stable. Two nitrogen atoms combine to form N2 molecules that stay in the atmosphere for millions of years.



The Alien Observatory — Planet Only a Billion Years Younger Than Big Bang Found in Milky Way’s M4 Globular Cluster



NASA's Hubble Space Telescope precisely measured the mass of the oldest known planet in our Milky Way galaxy near the core of the ancient globular star cluster M4, located 5,600 light-years away in the summer constellation Scorpius. At an estimated age of 13 billion years, the planet is more than twice as old as Earth's 4.5 billion years. It's about as old as a planet can be. It formed around a young, sun-like star barely 1 billion years after our universe's birth in the Big Bang. The ancient planet has had a remarkable history because it resides in an unlikely, rough neighborhood. It orbits a peculiar pair of burned-out stars in the crowded core of a cluster of more than 100,000 stars.


CERN’s Large Hadron Collider –“Has Awakened from ‘Hibernation’ To Renew Search for New Dimensions, Gravitons, and Tiny Black Holes”





The Large Hadron Collider (LHC) has awoken from ‘hibernation’ – and it’s ready to flip the switch and hunt for new dimensions, pushing the boundaries of our knowledge of particle physics. During the past winter, the LHC took a break from smashing particles together at velocities approaching the speed of light and is now gearing up to get back to work.


NASA’s Hubble Space Telescope –Star-Casted Shadows Reveal Alien Planets

Searching for planets around other stars is a tricky business. They're so small and faint that it's hard to spot them. But a possible planet in a nearby stellar system may be betraying its presence in a unique way: by a shadow that is sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding a young star.


Hubble Reveals Ghostly Core of the Supernova Seen by Chinese Astronomers in 1054




Though it's only 10 miles across, the amount of energy the pulsar at its core releases is enormous, lighting up the Crab Nebula until it shines 75,000 times more brightly than the sun. The nebula, one of our best-known and most stable neighbors in the winter sky, is shocking scientists with a propensity for fireworks—gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object. The discovery  is leading researchers to rethink their ideas of how cosmic particles are accelerated.
