The National Astronomical Observatory of Japan reports finding 83 previously-unknown super-massive black holes from the early Universe. These objects, seen in the form of powerful quasars, are observed as they appeared 13 billion years ago, just as the first stars, galaxies, and black holes were forming. Nearly every galaxy we see today is thought to have a super-massive black hole at its center, including our own Milky Way.Read More Astronomers Spot 83 Super-massive Black Holes from Earliest Days of the Universe
Using a revolutionary new technology known as a quantum computer, researchers have developed an answer to one of the great questions in cosmology. Astrophysicists have long questioned whether information about a particle, such as its spin, is lost or retained after it crosses into the area near a black hole from which light can not escape – the event horizon. This new research shows that information like this gets lost, as it is mixed in with all the energy and matter within the event horizon of a black hole. Individual bits in ordinary digital computers can only be set as ones and zeros, while qubits utilize quantum states to store data. Once fully developed, quantum computers will be able to take problems that would take millions of years for today’s computers to solve, and answer them in days.Read More Can Quantum Computing Unlock the Secrets of Black Holes?
Astronomers have long theorized that planetary systems can be affected by stars passing near solar systems. However, direct evidence of this has never been seen, until now.
Sitting 300 light years from Earth, the star HD 106906 is accompanied by a planet 11 times the size of Jupiter, orbiting the pair of binary stars 738 times further away than the distance between the Earth and the Sun. Computer simulations show that roughly 12 million years ago, another pair of stars passed the system, altering the orbit of this giant world, pulling it far from its stellar companions. Had the encounter not taken place, this world would have crashed into the stars around which it orbits.
A river of 4,000 stars has been detected just 330 light years from the Sun. This grouping is one billion years old, and has circled the outer edge of the Milky Way Galaxy four times since its formation. Astronomers found the formation using the Gaia space telescope, operated by the European Space Agency.Read More Billion-Year-Old River of Stars Seen Flowing Near the Sun
The Milky Way Galaxy is typically thought to be a flat, spiral disk. But, new research from astronomers at Macquarie University suggest our home galaxy is warped. By studying the positions of certain well-understood stars, researchers were able to create the first 3D model of our home galaxy. They found that the Milky Way has a slight “s” shape when viewed from the side. Torque caused by the movement of stars closer to the center the galaxy appear to be causing the effect.Read More It’s Not Just You – The Galaxy IS Warped, After All!
A supermassive black hole has been discovered within a tiny galaxy called UCD3. This finding, carried out by an international team at the Very Large Telescope in Chile, is only the fourth of its kind. Star families like UCD3 have masses tens of millions of times greater than the Sun, sitting in clusters just 300 light years in diameter.Read More Supermassive Black Hole Seen in Tiny Galaxy called UCD3
The Parker Solar Probe lifted off from Cape Canaveral on Sunday, August 12th, on its way to explore the Sun. During it’s seven-year mission, the vehicle will come closer to our parent star than any previous spacecraft, and experience temperatures of thousands of degrees. Astronomers hope the spacecraft will answer some long-standing questions in solar science.Read More Parker Solar Probe Lifts off on historic Journey to the Sun
Stephen Hawking passed away on March 14, 2018, leaving behind a legacy of works that rivals the greatest in history, including Galileo Galilei and Albert Einstein. However, this is not the only thing these three men had in common – they also shared remarkable coincidences about the times the each entered and left this world, […]Read More Galileo, Einstein, and Hawking – Tied Together by More than Physics
