How Will Our Sun Die?

May 10, 2018

Scientists say our Sun has been shining for about the last 4.6 billion years. They also say the Sun is expected to have enough hydrogen to fuel nuclear fusion in its core to allow it to continue shining as it has for about another 5 billion years. Along with creating solar energy, the Sun’s hydrogen […]

Einstein Proven Correct; Gravitational Waves Detected; Super Hot Planet

June 8, 2017

Einstein Theory Confirmed Again In his 1915 Theory of General Relativity, physicist Albert Einstein proposed that mass can bend space time. And he predicted that when a distant star’s light passed by a large object en route to the observer, the object’s gravity can bend and brighten the starlight like a magnifying lens. This effect, called […]

Insight Into Planetary Evolution – Dark Matter Rare in Old Galaxies

March 17, 2017

Scientists Gain New Insight into Planetary Evolution Scientists recently gained new insight into the evolution of planet formation by creating and studying a model of a fairly young solar system 300 light years from Earth. The nearly 13 million year-old planetary system circles a star known as HD 106906. The system features a surrounding planet […]

Did our Sun Snatch Planet 9 from Another Solar System?

June 3, 2016

Is it possible that the new-found theoretical Planet 9 is actually an exoplanet, a planet from another solar system? According to astronomers at Sweden’s Lund University, it’s “highly likely” that Planet 9 was actually “snatched” from another solar system by our young sun some 4.5 billion years ago, or within 100 million years after its formation. […]

Hubble Spots Farthest Supernova Yet

April 5, 2013

NASA’s Hubble Space Telescope has found the farthest known supernova discovered to date. Nicknamed “SN Wilson,” after the American President Woodrow Wilson, scientists say supernova UDS10Wil, exploded more than 10 billion years ago, about 3.77 billion years after the Big Bang. SN Wilson is in a special class of exploding stars known as “Type Ia […]
