10 Years of Revolutionary Solar Views from NASA’s STEREO Mission

STEREO 10 Years of Revolutionary Solar Views

Ten years ago the twin STEREO spacecraft joined a fleet of NASA spacecraft monitoring the sun and its influence on Earth and space – and they provided a new and unique perspective. Launched 10 years ago, on October 25, 2006, the twin spacecraft of NASA’s STEREO mission – short for Solar and Terrestrial Relations Observatory […]

Astronomers Discover Potential New Hunting Ground for Exoplanets

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 […]

Two-Pronged Immune Response Destroys Tumors

New Treatment Elicits Two-Pronged Immune Response That Destroys Tumors in Mice

Using a combination of four different therapies, researchers from MIT reveal a new treatment that destroys tumors in mice. Harnessing the body’s own immune system to destroy tumors is a tantalizing prospect that has yet to realize its full potential. However, a new advance from MIT may bring this strategy, known as cancer immunotherapy, closer […]

Cassini Views Saturn’s Dynamic Atmosphere

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 […]

Hubble Image of the Week – Globular Cluster NGC 362

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 Views the Red Spider Nebula

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 […]

Astronomers Reveal That Uranus May Have Two Undiscovered Moons

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 […]

Neuroscientists Identify Two Key Groups of Neurons That Help Regulate Appetite

Scientists Identify Two Key Groups of Neurons That Help Regulate Appetite

In a newly published study, Scientists from MIT have identify two key groups of neurons within the hypothalamus that help regulate appetite. MIT neuroscientists have discovered that brain cells called glial cells play a critical role in controlling appetite and feeding behavior. In a study of mice, the researchers found that activating these cells stimulates […]

Hotspots in Active Galactic Nucleus Cygnus A

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-Binary Questions What We Know About the Solar System

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 […]

Astronomers Discover Mysterious Cosmic Objects Erupting in X-rays

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, […]

New Study Shows Resistance to Cancer Drugs Runs Deeper Than a Single Gene

Resistance to Cancer Drugs Runs Deeper Than a Single Gene

A new study from Yale University shows that resistance to cancer drugs runs deeper than a single gene. Searching for more individual genes to predict responses to breast cancer therapy may not work, a new study suggests. Instead, scientists and clinicians need to pay attention to abnormalities in networks of genes, Yale researchers report in […]

Heme Molecule May Be The Key To More Effficient Batteries

Lithium-Oxygen (Li-O2) Batteries

New research from Yale University shows that a molecule that transports oxygen in blood could be key to developing the next generation of batteries. Lithium-oxygen (Li-O2) batteries have emerged in recent years as a possible successor to lithium-ion batteries — the industry standard for consumer electronics — due to their potential for holding a charge […]

Kepler Helps Show What Conditions Might Look Like on Various Hot Jupiters

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 to Date of Eta Carinae

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 […]

STEP Protein Linked to Alzheimer’s May Also Play a Role in Schizophrenia

Protein linked to Alzheimer’s May Also Play a Role in Schizophrenia

New research from Yale University shows that an increase in the STEP (STriatal-Enriched protein tyrosine Phosphatase) protein leads to a disruption of synaptic function and contributes to cognitive disorders. A specific protein implicated in the cognitive decline of Alzheimer’s disease also appears to play a role in genetic predisposition to schizophrenia, meaning that a drug […]

New Research Challenges Solar Radiation Models

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. […]

MAVEN Mission Provides Unprecedented Ultraviolet View of Mars

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 […]
