Image-Based Navigation Could Help Spacecraft Safely Land on the Moon

Engineers have demonstrated how a series of lunar images can be used to infer the direction that a spacecraft is moving. This technique, sometimes called visual odometry, allows navigation ...

Supercomputer Simulations Could Unlock Mystery of Moon's Formation

Astronomers have taken a step towards understanding how the Moon might have formed out of a giant collision between the early Earth and another massive object 4.5 billion years ...

Leaving So Soon? Unusual Planetary Nebula Fades Mere Decades After It Arrived

The tiny Stingray Nebula unexpectedly appeared in the 1980s is by far the youngest planetary nebula in our sky. But a team of astronomers recently ...

Voyager Spacecraft Detect New Type of Solar Electron Burst

The Voyager spacecraft continue to make discoveries even as they travel through interstellar space. In a new study, physicists report on the Voyagers' detection of cosmic ray electrons associated ...

Escape from Mars: How Water Fled the Red Planet

Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. Researchers have discovered a surprisingly large amount of water in the upper atmosphere of Mars, where it is ...

Birth of Magnetar from Colossal Collision Potentially Spotted for First Time

Researchers spotted a short gamma ray burst 10 times brighter than predicted. The mysterious brightness might signal the birth of a rare magnetar, formed from two neutron stars merging, which has ...

Prototype Fuel Gauge for Orbit

Liquids aren't as well behaved in space as they are on Earth. Inside a spacecraft, microgravity allows liquids to freely slosh and float about. This behavior has made fuel quantity in satellites ...

Researchers Model Source of Eruption on Jupiter's Moon Europa

A new model shows how brine on Jupiter's moon Europa can migrate within the icy shell to form pockets of salty water that erupt to the surface when freezing. The findings, which are important ...

Radioactive Elements May Be Crucial to the Habitability of Rocky Planets

The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from ...

Mining Rocks in Orbit Could Aid Deep Space Exploration

The first mining experiments conducted in space could pave the way for new technologies to help humans explore and establish settlements on distant worlds, a study ...

First Brown Dwarf Discovered by Radio Observations Confirmed

New research has led to the first direct discovery of a cold brown dwarf from its radio wavelength emission. Along with paving the way for future brown dwarf discoveries, this result is an important ...

Life is deeply dependent on water, but where does water come from? Based on new research, researchers believe it may emerge in connection with the formation of ...

Stellar Flares Can Lead to Diminishment of a Planet's Habitability

Researchers identified which stars were most likely to host habitable exoplanets based on the calculated erosion rates of the planetary ...

Seeing Dark Matter in a New Light

A small team of astronomers have found a new way to 'see' the elusive dark matter haloes that surround galaxies, with a new technique 10 times more precise than the previous-best ...

According to new research using data from NASA's retired planet-hunting mission, the Kepler space telescope, about half the stars similar in temperature to our Sun could have a rocky planet ...

Clay Subsoil at Earth's Driest Place May Signal Life on Mars

Diverse microbes discovered in the clay-rich, shallow soil layers in Chile's dry Atacama Desert suggest that similar deposits below the Martian surface may contain microorganisms, which could be ...

Microbial Space Travel on a Molecular Scale

Galactic cosmic and solar UV radiation, extreme vacuum, temperature fluctuations: how can microbes exposed to these challenges in space survive? Scientists investigated how the space-surviving ...

Supersonic Winds, Rocky Rains Forecasted on Lava Planet

Among the most extreme planets discovered beyond the edges of our solar system are lava planets: fiery hot worlds that circle so close to their host star that some regions are likely oceans of molten ...
