NASA, Citizen Scientists Discover Potential New Hunting Ground for Exoplanets

A group of citizen scientists and professional astronomers have discovered a star surrounded by the oldest known circumstellar disk — a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates. Led by Steven Silverberg of University of Oklahoma, the team […]

Astronomers Study Saturn's Fluid Dynamics

Astronomers are using Saturn’s clouds to study fluid dynamics, which seeks to understand the motion of gases and liquids. Saturn’s lack of a solid planetary surface (as on Earth, Mars or Venus) means that its atmosphere is free to flow around the planet essentially without obstruction. This is one factor that generates Saturn’s pattern of […]

New Hubble Image of NGC 362

This newly released Hubble image shows globular cluster NGC 362, which is located 27,000 light-years away. Globular clusters offer some of the most spectacular sights in the night sky. These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters — and […]

Hubble Image of the Red Spider Nebula

This newly released Hubble image shows the Red Spider Nebula, which is located some 3,000 light-years away in the constellation of Sagittarius. Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion […]

New Study Suggests Uranus May Have Two Undiscovered Moons

New research suggests that there could be two previously undiscovered moonlets orbiting near Uranus’ rings. Rob Chancia, a University of Idaho doctoral student, spotted key patterns in the rings while examining decades-old images of Uranus’ icy rings taken by Voyager 2 in 1986. He noticed the amount of ring material on the edge of the […]

Hotspots in an Active Galactic Nucleus

Astronomers used the Low Frequency Array radio telescope to obtain high spatial resolution images of the hotspots in Cygnus A, providing the first direct evidence that the spectral shape difference previously inferred is real. The nucleus of a so-called “active” galaxy contains a massive black hole that is vigorously accreting material. As a result, the […]

Discovery of First Binary-Binar Puts Solar System Formation Into Question

Binary system HD 87646 raises new questions about how protoplanetary disks form. Everything we know about the formation of solar systems might be wrong, says University of Florida astronomy professor Jian Ge and his postdoc, Bo Ma. They’ve discovered the first “binary–binary” – two massive companions around one star in a close binary system, one […]

Mysterious Cosmic Objects Erupting in X-rays

Using data from both Chandra and XMM-Newton, astronomers discovered two flaring objects in two different galaxies. These objects brighten in X-rays by a factor of 100 in about a minute before returning to previous level in about an hour. Astronomers have found a pair of extraordinary cosmic objects that dramatically burst in X-rays. This discovery, […]

Kepler Reveals Cloudy Nights and Sunny Days on Distant Hot Jupiters

Data from NASA’s Kepler Space Telescope and computer modeling show an approximation of what various hot Jupiters might look like. The weather forecast for faraway, blistering planets called “hot Jupiters” might go something like this: Cloudy nights and sunny days, with a high of 2,400 degrees Fahrenheit (about 1,300 degrees Celsius, or 1,600 Kelvin). These […]

VLT Provides Highest Resolution Image of Eta Carinae

Using the Very Large Telescope Interferometer, a team of astronomers reveals the Eta Carinae star system in the greatest detail ever achieved. High-resolution images reveal new and unexpected structures within the Eta Carinae binary system, including in the area between the two stars where extremely high velocity stellar winds are colliding. These new insights into […]

Wayward Field Lines Challenge Solar Radiation Models

This video compares the two models for particle distribution over the course of just three hours after an SEP event. The white line represents a magnetic field line, the general path that the SEPs follow. The line starts at an SEP event at the sun, and leads the particles in a spiral around the sun. […]

NASAs-MAVEN-Mission-Gives-Unprecedented-View-of-Mars

New images from the MAVEN mission show the ultraviolet glow from the Martian atmosphere in unprecedented detail, revealing dynamic, previously invisible behavior. They include the first images of “nightglow” that can be used to show how winds circulate at high altitudes. Additionally, dayside ultraviolet imagery from the spacecraft shows how ozone amounts change over the […]

Cassini Views Saturn's Moon Pandora

This new Cassini image shows Saturn’s moon Pandora in isolation beside Saturn’s kinked and constantly changing F ring. Pandora (near upper right) is 50 miles (81 kilometers) wide. The moon has an elongated, potato-like shape. Two faint ringlets are visible within the Encke Gap, near lower left. The gap is about 202 miles (325 kilometers) […]

Studying a Star's Environment from Light Curves

Using the ALMA telescopes, astronomers discovered a circumstellar disk around the star EPIC 204278916 and offer several explanations for the dips including that they are caused by clumps of material in the warped inner portion of the disk. There are now about 2700 confirmed exoplanets discovered by transiting techniques including those used with the Kepler […]

New Hubble Image of NGC 299

This newly released Hubble image shows open star cluster NGC 299. It may be famous for hosting spectacular sights such as the Tucana Dwarf Galaxy and 47 Tucanae, the second brightest globular cluster in the night sky, but the southern constellation of Tucana (The Toucan) also possesses a variety of unsung cosmic beauties. One such […]

VISTA Discovers Remains of Archaic Globular Star Cluster

Using ESO’s infrared VISTA telescope, astronomers have discovered ancient stars, of a type known as RR Lyrae, in the center of the Milky Way for the first time. RR Lyrae stars typically reside in ancient stellar populations over 10 billion years old. Their discovery suggests that the bulging center of the Milky Way likely grew […]

Hubble Reveals Observable Universe Contains 10 Times More Galaxies Than Previously Thought

A new study of Hubble’s deep-field surveys reveals that at least 10 times more galaxies exist in the observable universe than astronomers thought. The universe suddenly looks a lot more crowded, thanks to a deep-sky census assembled from surveys taken by NASA’s Hubble Space Telescope and other observatories. Astronomers came to the surprising conclusion that […]
