Astronomers Measure Kepler 11145123 with Unprecedented Precision

Astronomers Measure the Shape of Kepler 11145123

In a newly published study, scientists from the Max Planck Institute and the University of Göttingen measure the shape of Kepler 11145123 with unprecedented precision. Stars are not perfect spheres. While they rotate, they become flat due to the centrifugal force. A team of researchers around Laurent Gizon from the Max Planck Institute for Solar […]

Researchers Derive a Formula for Tracking the Flow of Quantum Information

New Formula Tracks the Flow of Quantum Information

A team of reserchers has developed a formula for understanding where quantum objects land when they are transmitted. If objects in motion are like rainwater flowing through a gutter and landing in a puddle, then quantum objects in motion are like rainwater that might end up in a bunch of puddles, all at once. Figuring […]

NASA’s SOFIA Set To Study New Frontiers in the Solar System and Beyond

SOFIA Observatory Expanding New Frontiers in the Solar System and Beyond

NASA’s SOFIA flying Observatory set to study planets, comets and asteroids orbiting other stars and supermassive black holes. NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, will soon be studying Neptune’s giant moon, Triton, and following-up on Hubble’s recent sighting of water plumes on Jupiter’s moon Europa. According to recently completed plans for the 2017 observing […]

‘Great Valley’ Provides More Evidence That Mercury is Shrinking

Astronomers Reveal Great Valley on Mercury

A newly discovered “great valley” in the southern hemisphere of Mercury provides more evidence that the small planet closest to the sun is shrinking. Scientists used stereo images from NASA’s MESSENGER spacecraft to create a high-resolution topo map that revealed the broad valley — more than 620 miles (1,000 kilometers) long — extending into the […]

MIT Chemists Reveal Bacterial Enzyme That Can Produce Biodegradable Plastics

Chemists Discover Structure of Bacterial Enzyme That Generates Useful Polymers

Researchers at MIT have determined the structure of a bacterial enzyme that can produce biodegradable plastics, an advance that could help chemical engineers tweak the enzyme to make it even more industrially useful. The enzyme generates long polymer chains that can form either hard or soft plastics, depending on the starting materials that go into […]

New Catalyst Promotes Carbon Dioxide Conversion into Fuels

Turning Greenhouse Gas Into Gasoline

Scientists at MIT have developed a new catalyst material that provides design principles for producing fuels from carbon dioxide emissions. The findings suggest a route toward using the world’s existing infrastructure for fuel storage and distribution, without adding net greenhouse emissions to the atmosphere. The new catalyst takes the process only through its first stage […]

GASS 3505: A Hydrogen Rich, Passive Galaxy

Hydrogen Rich Passive Galaxy GASS-3505

New research from the Harvard-Smithsonian Center for Astrophysics reveals that the star formation in GASS 3505 is very weak, less than about 0.1 solar-masses per year. Cold gas in the form of neutral hydrogen atoms provides the reservoir for star formation in galaxies from the distant to the nearby Universe. Understanding how it accretes onto […]

Electricity-Powered Molecular Catalysts May Improve Fuel Cells

Better Catalysts Make Better Fuel Cells

A team of chemists from Yale University have developed a framework for designing electricity-powered molecular catalysts that may prove vital for a new generation of fuel cells. Also called electrocatalysts, these substances boost the rate of a chemical reaction by decreasing the energy input along the way. In fuel cells, electrocatalysts can be used to […]

Cassini Spacecraft Views Saturn’s ‘Watercolor’ Swirl

Cassini Views Saturn's 'Watercolor' Swirls

In this newly released image from the Cassini Spacecraft you can see Saturn’s north polar region, which somewhat resemble the brushwork in a watercolor painting. Each latitudinal band represents air flowing at different speeds, and clouds at different heights, compared to neighboring bands. Where they meet and flow past each other, the bands’ interactions produce […]

Hubble Image of the Week – Irregular Dwarf Galaxy NGC 4789A

Hubble Views Irregular Dwarf Galaxy NGC 4789A

This newly released Hubble image shows irregular dwarf galaxy NGC 4789A, which is located in the constellation of Coma Berenices. It certainly lives up to its name — the stars that call this galaxy home are smeared out across the sky in an apparently disorderly and irregular jumble, giving NGC 4789A a far more subtle […]

Inhibiting the AIM2 Pathway Could Potentially Limit Radiation Damage to Cells

Study Pinpoints Protein That Detects Damage from Radiation

New research from Yale University shows that a drug that blocks or inhibits the AIM2 pathway could potentially limit the deleterious side effect of chemotherapy or radiotherapy on cancer patients. High doses of radiation from cancer treatment can cause severe damage to cells and tissues, resulting in injury to bone marrow and the gastrointestinal tract. […]

Get Ready for the November Supermoon

November Supermoon

Don’t miss the upcoming supermoon on Monday, November 14. It will be the closest full moon to Earth since 1948 and we won’t see another supermoon like this until 2034. The moon’s orbit around Earth is slightly elliptical so sometimes it is closer and sometimes it’s farther away. When the moon is full as it […]

Astronomers Explain Mysterious Dimming of Markarian 1018

Markarian 1018 Black Hole Dims Brilliant Galaxy

By combining data from Chandra, VLT and several other telescopes, astronomers reveal that the dimming of Markarian 1018 arises from the black hole at the center being deprived of enough fuel to illuminate its surroundings. Astronomers may have solved the mystery of the peculiar volatile behavior of a supermassive black hole at the center of […]

Spitzer and Swift Observe Microlensing Event, Pinpoint Brown Dwarf

NASA Pinpoints Elusive Brown Dwarf

Using NASA’s Spitzer and Swift Space Telescopes, astronomers discovered a brown dwarf when it and its star passed between Earth and a much more distant star in our galaxy. This passing created a microlensing event, where the gravity of the system amplified the light of the background star over the course of several weeks. In […]
