Moon-forming disk discovered around distant planet

Moon-forming disk discovered around distant planet Using Earth’s most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one that is believed to have birthed the moons of Jupiter. phys.org Go to Source

Hubble discovers mysterious black hole disc

Hubble discovers mysterious black hole disc Astronomers using the NASA/ESA Hubble Space Telescope have observed an unexpected thin disc of material encircling a supermassive black hole at the heart of the spiral galaxy NGC 3147, located 130 million light-years away. phys.org Go to Source

Astronomers find evidence of atmosphere-like envelopes around galaxies

Astronomers find evidence of atmosphere-like envelopes around galaxies A new study by researchers at the University of Hertfordshire, published today in journal Astronomy and Astrophysics, has found evidence that the gaseous envelopes around larger galaxies are similar to the state of Earth’s atmosphere. phys.org Go to Source

HSC16aay is a Type IIn supernova, study suggests

HSC16aay is a Type IIn supernova, study suggests New research presented by an international team of astronomers suggests that a recently detected transient, designated HSC16aay, is a Type IIn supernova. A research paper reporting the discovery and detailing the finding, was published July 2 on the arXiv pre-print server. phys.org Go to Source

New Study Shows How Breaching “Carbon Threshold” Could Trigger Mass Extinction in Earth’s Oceans

New Study Shows How Breaching “Carbon Threshold” Could Trigger Mass Extinction in Earth’s Oceans A NASA and NSF-supported study by an MIT geophysicist indicates that carbon emissions could push the Earth’s oceans past a “threshold”, leading to a possible mass extinction. The post New Study Shows How Breaching “Carbon Threshold” Could Trigger Mass Extinction in […]

Exoplanet evolution: Astronomers expand cosmic ‘cheat sheet’

Exoplanet evolution: Astronomers expand cosmic ‘cheat sheet’ Cornell astronomers have reached into nature’s color palette from early Earth to create a cosmic “cheat sheet” for looking at distant worlds. By correlating tints and hues, researchers aim to understand where discovered exoplanets may reasonably fall along their own evolutionary spectrum. phys.org Go to Source

Mars’ North Pole is Doing the Dust Storms Thing Again

Mars’ North Pole is Doing the Dust Storms Thing Again It’s easy to take for granted the detailed, almost real-time knowledge of Mars that we have at our fingertips. After all, in the not-too-distant past, Mars was largely mysterious. All we had were ground-based images of the planet. Now? Now we have daily weather reports […]

Interstellar iron isn’t missing, it’s just hiding in plain sight

Interstellar iron isn’t missing, it’s just hiding in plain sight Astrophysicists know that iron (chemical symbol: Fe) is one of the most abundant elements in the universe, after lightweight elements such as hydrogen, carbon, and oxygen. Iron is most commonly found in gaseous form in stars such as the Sun, and in more condensed form […]

Our Guide to Saturn Opposition Season 2019

Our Guide to Saturn Opposition Season 2019 Saturn opposition season never disappoints. Slowly, one by one, the planets are returning to the dusk sky. In June, we had Jupiter reach opposition on June 10th. Now, although Mercury and Mars are fleeing the evening scene low to the west at dusk and Venus lingers low in […]

Djorgovski 2 is a moderately metal-poor globular cluster, study finds

Djorgovski 2 is a moderately metal-poor globular cluster, study finds Based on data from the Hubble Space Telescope (HST) and from the Very Large Telescope (VLT), astronomers have gained insights into a galactic globular cluster known as Djorgovski 2. Besides determining fundamental parameters of the object, the new research classified Djorgovski 2 as a moderately […]

Discovering exoplanets with gravitational waves

Discovering exoplanets with gravitational waves In a recent paper in Nature Astronomy, researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam and from the French Alternative Energies and Atomic Energy Commission (CEA) in Saclay, Paris suggest how the planned space-based gravitational-wave observatory LISA can detect exoplanets orbiting white dwarf binaries […]

3 sky surveys completed in preparation for Dark Energy Spectroscopic Instrument

3 sky surveys completed in preparation for Dark Energy Spectroscopic Instrument It took three sky surveys—conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights—to prepare for a new project that will create the largest 3-D map of the universe’s galaxies and glean new insights about the […]

Powering the extreme jets of active galaxies

Powering the extreme jets of active galaxies An active galaxy nucleus (AGN) contains a supermassive black hole that is vigorously accreting material. It typically ejects jets of particles that move at close to the speed of light, radiating across many wavelengths, in particular the X-ray, in processes are among the most energetic phenomena in the […]
