Cosmic Inflation Confirmed by Gravitational Waves

For decades now cosmologists have widely believed that the cosmic inflationary model of the big bang is correct. However, actually proving that has been one of the most sought-after observations in modern Physics. Now astrophysicists have found definitive proof that cosmic inflation helped shape the universe during the earliest moment following the big bang. This week the scientists of the …

Asteroid 2014: Cosmic Monster Missed Earth This Morning

A couple million miles may not sound like much of a “close call” with an asteroid. But compare it to the vast and empty light years upon light years surrounding this oxygenated rock ball we ride around on in infinite space, and 1.6 million miles isn’t much wiggle room between us and a structure racing past at 27,000 miles per …

Three Ancient Galaxies Spotted Merging

Astronomers this week revealed that they have spotted three ancient galaxies that appear to be merging. The observations, which were made using both the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) are recorded in a paper to be published in The Astrophysical Journal. The three galaxies are located inside a large gas cloud that is located almost …

Astronomers Confirm Milky Way Particle Jet

Astronomers this week have revealed the confirmation that the black hole at the center of our galaxy is ejecting a stream of high-energy particles. The new findings have been published in The Astrophysical Journal. Researchers for some time have assumed that our Milky Way galaxy has a jet of particles spouting from its center, much like other galaxies similar to …

Astronomers Find “Twist” in Cosmic Microwave Background

Astronomers this week announced that they have found a “twist” in the cosmic microwave background (CMB) radiation that blankets the universe. To be more specific, researchers have detected B-mode polarization in the CMB caused by gravitational lensing. What this means is that astronomers have discovered just how the earliest light in the universe was deflected by galaxies and dark matter …

NASA Measures Fast-Spinning, Supermassive Black Hole

NASA today revealed that it has teamed up with the European Space Agency (ESA) to, for the first time, measure the spin rate of a supermassive black hole. Using NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and the ESA’s XMM-Newton, astronomers were able to observe the black hole that lies at the center of the galaxy NGC 1365. The object was …

NASA Joins Euclid Dark Universe Mission

NASA announced this week that it has joined the European Space Agency’s (ESA) Euclid mission. The mission will investigate dark matter and dark energy throughout the universe. In 2020, the mission will launch the Euclid space telescope, which will spend six years mapping and measuring as many as 2 billion galaxies that cover one-third of the sky. The hope is …

Hubble Constant More Accurately Measured by Astronomers

Astronomers have used NASA’s Spitzer Space Telescope to obtain the most precise measurement yet of the Hubble constant, which is the rate at which the universe is expanding. The Hubble constant is named for Edwin Hubble, the astronomer who discovered that the universe is expanding. The new measurement improves the accuracy of the previous most-accurate measurement (from the Hubble Space …
