Gaia Space Telescope Rocks the Science of Asteroids

The European Gaia space mission has produced an unprecedented amount of new, improved, and detailed data for almost two billion objects in the Milky Way galaxy and the surrounding cosmos. The Gaia ...

New Control Technique Uses Solar Panels to Reach Desired Mars Orbit

Aerospace engineers have developed a way to use articulated solar panels to steer the satellite during aerobraking, reducing the number of passes needed, resulting in potential savings in propellant, ...

Spotted: An Exoplanet With the Potential to Form Moons

New high-resolution observations clearly show a moon-forming region around exoplanet PDS 70c. The observations have allowed astronomers to determine the ring-shaped region's size and mass for the ...

Scientists Use NASA Satellite Data to Track Ocean Microplastics from Space

Scientists have developed an innovative way to use NASA satellite data to track the movement of tiny pieces of plastic in the ...

Dark Coating Can Reduce Satellite Reflectivity

Observations confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous artificial satellites in orbit could impair astronomical observations, but these ...

The Craters on Earth

A two-volume atlas presents and explains the impact sites of meteorites and asteroids ...

Secret Weapon to Stop Invasive Honeysuckle: Satellites

Researchers found that satellite imagery can identify non-native and invasive Amur honeysuckle, an ornamental shrub introduced from Asia that has spread in forests across much of the United ...

Huge Ring-Like Structure on Ganymede's Surface May Have Been Caused by Violent Impact

Image data reanalysis has revealed that ancient tectonic troughs are concentrically distributed across almost the entire surface of Jupiter's moon Ganymede. Computer simulation results suggest ...

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. ...

Using Sunlight to Save Satellites from a Fate of 'Space Junk'

Satellites are almost always illuminated by the sun, apart from short transitions to Earth's shadow. The light that a satellite reflects can help reveal the solution to a structural ...

Speed of Space Storms Key to Protecting Astronauts and Satellites from Radiation

Measuring the speed of coronal mass ejections (CMEs) as they erupt from the sun, in addition to their size, found to be crucial in providing accurate early warnings that keep astronauts and ...

Solving the Space Junk Problem

Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is ...

The Milky Way's Satellites Help Reveal Link Between Dark Matter Halos and Galaxy Formation

Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way ...

Safety Zone Saves Giant Moons from Fatal Plunge

Numerical simulations showed that the temperature gradient in the disk of gas around a young gas giant planet could play a critical role in the development of a satellite system dominated by a single ...

Impact of Satellite Constellations on Astronomical Observations

Astronomers have recently raised concerns about the impact of satellite mega-constellations on scientific research. To better understand the effect these constellations could have on astronomical ...

Space Weather Model Gives Earlier Warning of Satellite-Killing Radiation Storms

A new machine-learning computer model accurately predicts damaging radiation storms caused by the Van Allen belts two days prior to the storm, the most advanced notice to date, according to a new ...

New Patented Invention Stabilizes, Rotates Satellites

Many satellites are in space to take photos. But a vibrating satellite, like a camera in shaky hands, can't get a sharp image. Pointing it at a precise location to take a photo or perform ...

Satellite Constellations Harvest Energy for Near-Total Global Coverage

Scientists have discovered the right combination of factors to make a four-satellite constellation possible, which could drive advances in telecommunication, navigation and remote ...

Finding a Killer Electron Hot Spot in Earth's Van Allen Radiation Belts

JAXA and NASA satellite observations show where killer electrons are generated in the Van Allen radiation belts surrounding ...

No 'Clouded' Judgments: Geostationary Satellite an Alternative to Monitor Land Surfaces

Environmental scientists are always in search of new tools that can better characterize the Earth's surface. Researchers have now reported that Himawari-8, a new-generation geostationary ...

Satellite Broken? Smart Satellites to the Rescue

Scientists are developing robotic networks that can work independently but collaboratively on a common task. The goal? To make smart satellites that can repair other satellites in ...

Satellites Are Key to Monitoring Ocean Carbon

Satellites now play a key role in monitoring carbon levels in the oceans, but we are only just beginning to understand their full ...

The Milky Way Kidnapped Several Tiny Galaxies from Its Neighbor

A team of astronomers has discovered that several of the small -- or 'dwarf' -- galaxies orbiting the Milky Way were likely stolen from the Large Magellanic Cloud, including several ...

Sun's Solar Wind and Plasma 'Burps' Created on Earth

A new study by physicists mimicked solar winds in the lab, confirming how they develop and providing an Earth-bound model for the future study of solar ...
