NASA’s Cassini Spacecraft Begins Final Year of Its Voyage

Cassini Begins Final Year at Saturn

After more than 12 years of exploring Saturn, NASA’s Cassini Spacecraft has entered the final year of its voyage. The conclusion of the historic scientific odyssey is planned for September 2017, but not before the spacecraft completes a daring two-part endgame. Beginning on November 30, Cassini’s orbit will send the spacecraft just past the outer […]

Chandra Detects X-Rays from Pluto

Astronomers Shed New Light on Pluto

Using Chandra, a team of astronomers has detected X-rays from Pluto for the first time. This X-ray emission comes from the interaction between Pluto’s atmosphere and solar wind. New Chandra observations offer new insight into the space environment surrounding Pluto, the largest and best-known object in the solar system’s outermost regions. While NASA’s New Horizons […]

New T Cell Subsets Have Potential to Improve Cellular Therapy for Cancer

Researchers Identify New T cell Subsets with Potential to Improve Cellular Therapy for Cancer

Researchers from the Yale Cancer Center have identified that two genes, NR4A1 and ABC transporters, mark a distinct subset of quiescent T cells within human tissues, and have developed methods to mobilize them into circulation for potential application in adoptive T cell therapy of cancer. The study is published in the Journal of Clinical Investigation. […]

Charon’s Polar Coloring the Result of Seasonally Cold-Trapped Volatiles

Charon’s Polar Coloring Comes from Pluto

New research reveals that Charon’s reddish polar coloring comes from Pluto itself. In June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it elsewhere in our solar system, and they couldn’t […]

Speckle Imaging Helps Provide the Highest-Resolution Images Available of TRAPPIST-1

The TRAPPIST-1 System

Using the Gemini-South telescope and a speckle imaging camera, a team of astronomers have obtained the highest-resolution images available of TRAPPIST-1. When it comes to exoplanets, astronomers have realized that they only know the properties of the planets they discover as well as they know the properties of the stars being orbited. For a planet’s […]

Mars Reconnaissance Orbiter Views a Streamlined Form in Lethe Vallis, Mars

New Image of Lethe Vallis on Mars

This newly released image from NASA’s Mars Reconnaissance Orbiter shows a portion of Lethe Vallis, an outflow channel that also transported lava. This image was acquired at 15:16 local Mars time on May 6, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. Another investigation of this area (Balme […]

MIT Biologists Reveal How lncRNA Helps to Control Cell Fate

Biologists Discover How RNA Helps Control Cell Fate

New research details how biologists from MIT deciphered the structure of one type of long noncoding RNA and used that information to figure out how it interacts with a cellular protein to control the development of heart muscle cells. Several years ago, biologists discovered a new type of genetic material known as long noncoding RNA. […]

Yale Study Shows Video Games Can Have Lasting Impact on Learning

Video Games Have Lasting Impact on Learning

New research from Yale University shows that a computer-based brain training program helps improve student performance in reading and math — in some cases even more than individualized tutoring. The new study is published in Scientific Reports. In a study of more than 500 second graders, math and reading scores on school- administered tests increased […]

A Riddle for Our Time – Astronomers Examine Cosmic History

The Dimensionless Age of the Universe: a Riddle for Our Time

In a newly published study, a team of astronomers call attention to a neglected riddle of the expansion of the universe: although cosmic acceleration might have started at any time, curiously it has happened in our own time. One of the most remarkable successes of astrophysics in the last century was its discovery that the […]

Spitzer Telescope Views ‘Enterprise’ Nebulae

Spitzer Views the Enterprise Nebulae

A new infrared image from NASA’s Spitzer Space Telescope may remind fans of Star Trek. Since ancient times, people have imagined familiar objects when gazing at the heavens. There are many examples of this phenomenon, known as pareidolia, including the constellations and the well-known nebulae named Ant, Stingray and Hourglass. On the right of the […]

Astronomers Detect Young Magnetar in Supernova Remnant, Likely the Slowest Pulsar Ever Discovered

Chandra Discovers Young Magnetar

Astronomers may have detected the slowest spinning neutron star to date. The object is in the middle of the RCW 103 supernova remnant, which is about 10,700 light years from Earth. While other neutron stars spin multiple times a minute, this object only rotates once about every 6.5 hours. Using NASA’s Chandra X-ray Observatory and […]

New Cassini Images Show Titan’s Dunes and Other Features

New Images Show Titans Dunes and Other Features

New images from NASA’s Cassini spacecraft peer through the haze that surrounds Titan, revealing dunes and other interesting features. This video focuses on Shangri-la, a large, dark area on Titan filled with dunes. The long, linear dunes are thought to be comprised of grains derived from hydrocarbons that have settled out of Titan’s atmosphere. Cassini […]

Astronomers Discover an Unusual Mix of Stars in Terzan 5

Scientists Discover Rare Fossil Relic of Early Milky Way

An international team of astronomers has revealed the unusual mix of stars in the stellar cluster known as Terzan 5. The new results indicate that Terzan 5 is in fact one of the bulge’s primordial building blocks, most likely the relic of the very early days of the Milky Way. Using ESO’s Very Large Telescope […]

Mysterious X-Ray Signal Most Likely from Sulfur Ions, Not Dark Matter

Mysterious X-Ray Signal Most Likely Originates from Sulfur Ions

New research shows that a recently discovered mysterious X-ray signal most likely originates from sulfur ions, not from dark matter. A mysterious X-ray signal from clusters of galaxies recently caused some excitement among astronomers: Does it perhaps originate from dark matter, which makes up around 80 percent of the matter in the universe, but which […]

Why So Blue? ESO Views Spiral Galaxy Messier 98

Spiral Galaxy Messier 98

This newly released image shows spiral galaxy Messier 98, which is located about 50 million light-years away. The color blue has many associations — coldness, sadness, serenity. However, the color holds a completely different meaning for astronomers, as demonstrated by the edge-on spiral galaxy Messier 98. Messier 98, also known as NGC 4192, is located […]
