Evidence of 6 New Binary Black Hole Mergers Within LVC Data

Scholars recently submitted an article announcing the discovery of six new binary black hole mergers, which exceed the detection thresholds defined by the LIGO-Virgo Collaboration. Applying a unique ... read more

New measurements from NASA's Hubble Space Telescope confirm that the Universe is expanding about 9% faster than expected based on its trajectory seen shortly after the big bang, astronomers ... read more

This incredible image of the hourglass-shaped Southern Crab Nebula was taken to mark the NASA/ESA Hubble Space Telescope's 29th anniversary in space. The nebula, created by a binary star system, ... read more

Origin of Photons in Mysterious Gamma-Ray Bursts

Scientists have used simulations to show that the photons emitted by long gamma-ray bursts -- one of the most energetic events to take place in the universe -- originate in the photosphere -- the ... read more

The Rise and Fall of Ziggy Star Formation and the Rich Dust from Ancient Stars

Researchers have detected a radio signal from abundant interstellar dust in MACS0416_Y1, a galaxy 13.2 billion light-years away in the constellation Eridanus. Standard models can't explain this ... read more

How Heavy Elements Come About in the Universe

Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons). This occurs at extremely high temperatures, but at ... read more

Understanding and Controlling the Molecule That Made the Universe

Trihydrogen, or H3+, is acknowledged by many scientists as the molecule that made the universe. Researchers employed high-speed lasers to shine a spotlight on the mechanisms that are key in H3+ ... read more

Astronomers Discover 83 Supermassive Black Holes in the Early Universe

Astronomers have discovered 83 quasars powered by supermassive black holes that were formed when the universe was only 5 percent of its current ... read more

Investigation of the Origin of Heavy Elements

Atomic physicists working on nuclear fusion research succeeded in computing the world's highest accuracy atomic data of neodymium ions which is used in analysis of the light from a binary ... read more

What Does the Milky Way Weigh? Hubble and Gaia Investigate

We can't put the whole Milky Way on a scale, but astronomers have been able to come up with one of the most accurate measurements yet of our galaxy's mass, using NASA's Hubble Space ... read more

Anemic Galaxy Reveals Deficiencies in Ultra-Diffuse Galaxy Formation Theory

A team of astronomers have discovered a bizarre, solitary ultra-diffuse galaxy (UDG). This transparent, ghost-like galaxy, named DGSAT I, contradicts the current theory on the formation of UDGs. All ... read more

ALMA Differentiates Two Birth Cries from a Single Star

Astronomers have unveiled the enigmatic origins of two different gas streams from a baby star. Using ALMA, they found that the slow outflow and the high speed jet from a protostar have misaligned ... read more

New NASA Mission Could Find More Than 1,000 Planets

A NASA telescope that will give humans the largest, deepest, clearest picture of the universe since the Hubble Space Telescope could find as many as 1,400 new planets outside Earth's solar ... read more

Gravitational Waves Will Settle Cosmic Conundrum

Measurements of gravitational waves from approximately 50 binary neutron stars over the next decade will definitively resolve an intense debate about how quickly our universe is expanding, according ... read more

Spacecraft Measurements Reveal Mechanism of Solar Wind Heating

A new study describes the first direct measurement of how energy is transferred from the chaotic electromagnetic fields in space to the particles that make up the solar wind, leading to the heating ... read more

Scientists Observe a New Form of Strange Matter

In a discovery that could provide new insights into the origin of mass in the universe following the Big Bang, scientists have used experiments with kaons and helium-3 to experimentally demonstrate, ... read more

How to Escape a Black Hole: Simulations Provide New Clues About Powerful Plasma Jets

New simulations have combined decades-old theories to provide new insight about the driving mechanisms in plasma jets that allows them to steal energy from black holes' powerful gravitational ... read more

Making the Hubble's Deepest Images Even Deeper

It has taken researchers almost three years to produce the deepest image of the Universe ever taken from space, by recovering a large quantity of 'lost' light around the largest galaxies in ... read more

Birth of Massive Black Holes in the Early Universe

The light released from around the first massive black holes in the universe is so intense that it is able to reach telescopes across the entire expanse of the universe. Incredibly, the light from ... read more

Seeing Double Could Help Resolve Dispute About How Fast the Universe Is Expanding

How fast the universe is expanding has been puzzling astronomers for almost a century. Different studies keep coming up with different answers -- which has some researchers wondering if they've ... read more
