Sun’s Bubble of Influence May Be Shaped Like a Deflated Croissant

Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA ...

The Quiet Sun Is Much More Active Than We Thought

For a long time, researchers have believed that there is not much of interest going on in the Sun during the passive period, therefore not worth studying. Now this assumption is showed to be false. ...

Iron-Rich Meteorites Show Record of Core Crystallization in System's Oldest Planetesimals

New work uncovers new details about our Solar System's oldest planetary objects, which broke apart in long-ago collisions to form iron-rich ...
A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to ...

The first images from Solar Orbiter, a new Sun-observing mission by ESA and NASA, have revealed omnipresent miniature solar flares, dubbed 'campfires', near the surface of our closest ...

Gigantic, Red and Full of Spots

Starspots are more common among red giant stars than previously thought. Astronomers report that approximately eight percent of red giants exhibit such spots. Although red giants are generally ...

Scientists have developed a new method to find black holes in the outer solar system, and along with it, determine once-and-for-all the true nature of the hypothesized Planet ...

Enormous 'Superflare' Detected on Nearby Star

Astronomers succeeded in detecting 12 stellar flare phenomena on AD Leonis. One of these flares was 20 times larger than those emitted by our own sun, categorizing it a 'superflare'. ...

The Collective Power of the Solar System's Dark, Icy Bodies

Two new studies by researchers at the University of Colorado Boulder may help to solve one of the biggest mysteries about the dark, icy bodies of the outer solar system: why so many of them ...

A new analysis of white dwarf stars supports their role as a key source of carbon in galaxies. Every carbon atom in the universe was created by stars, but astrophysicists still debate which types of ...

A Binary Star as a Cosmic Particle Accelerator

Scientists have identified the binary star Eta Carinae as a new kind of source for very high-energy (VHE) cosmic gamma-radiation. Eta Carinae is located 7500 lightyears away in the constellation ...

Hidden Sources of Mysterious Cosmic Neutrinos Seen on Earth

A new model points to the coronoe of supermassive black holes at the cores of active galaxies to help explain the excess neutrinos observed by the IceCube Neutrino ...

On a quest to find the Universe's largest black holes, researchers identify the center of the solar system within 100 ...

First Measurement of Spin-Orbit Alignment on Planet Beta Pictoris B

Astronomers have made the first measurement of spin-orbit alignment for a distant 'super-Jupiter' planet, demonstrating a technique that could enable breakthroughs in the quest to ...

The Magnetic History of Ice

The history of our planet has been written, among other things, in the periodic reversal of its magnetic poles. Scientists propose a new means of reading this historic record: in ice. Their findings ...

The sun's convection zone plays a key role in the generation and evolution of the Sun's magnetic field. Analyzing data sets spanning more than 20 years, researchers have obtained the most ...

Super-Earths Discovered Orbiting Nearby Red Dwarf

The nearest exoplanets to us provide the best opportunities for study, including searching for evidence of life outside the Solar System. Astronomers have now detected a system of super-Earth planets ...

Hubble Watches the 'Flapping' of Cosmic Bat Shadow in the Serpens Nebula

The young star HBC 672 is known by its nickname of Bat Shadow because of its wing-like shadow feature. The NASA/ESA Hubble Space Telescope has now observed a curious ''flapping'' ...

Rogue's Gallery of Dusty Star Systems Reveals Exoplanet Nurseries

The Gemini Planet Imager on the Gemini South telescope looked at 104 young, nearby stars, 10-100 million years old, in search of debris disks. It found 26, 25 of which had inner holes indicating a ...

The discovery could help astronomers understand how planets like Earth form and ...

Mystery Astronomical Object in 'Mass Gap': Neutron Star? Black Hole?

Researchers have discovered what is either the heaviest known neutron star, or the lightest black ...

A new study suggests that Pluto and other large Kuiper belt objects started out with liquid oceans which have been slowly freezing over ...

Scientists Provide New Explanation for the Far Side of the Moon's Strange Asymmetry

The Earth-Moon system's history remains mysterious. Scientists believe the two formed when a Mars-sized body collided with the proto-Earth. Earth ended up being the larger daughter of this ...

Are Planets With Oceans Common in the Galaxy? It's Likely, Scientists Find

Several years ago, planetary scientists began to wonder whether any of the more than 4,000 known exoplanets, or planets beyond our solar system, might resemble some of the watery moons around Jupiter ...
