Newly discovered comet is likely interstellar visitor

A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system. The object—designated C/2019 Q4 (Borisov) - was discovered on Aug. 30, 2019, ...

NASA's WFIRST will help uncover the universe's fate

Scientists have discovered that a mysterious pressure dubbed "dark energy" makes up about 68% of the total energy content of the cosmos, but so far we don't know much more about it. Exploring the nature of dark energy is ...

VISTA unveils a new image of the Large Magellanic Cloud

The Large Magellanic Cloud, or LMC, is one of our nearest galactic neighbors, at only 163,000 light years from Earth. With its sibling the Small Magellanic Cloud, these are among the nearest dwarf satellite galaxies to the ...

Image: Hubble glimpses faint galaxy

This image, taken with the NASA/ESA Hubble Space Telescope, focuses on an object named UGC 695, which is located 30 million light-years away within the constellation Cetus (the Sea Monster), also known as the Whale. A bounty ...

NASA's Mars 2020 comes full circle

Engineers took NASA's Mars 2020 for a spin on Aug. 29, 2019. The 2,300-pound (1,040-kilogram) Martian vehicle was rotated clockwise and counterclockwise at about 1 revolution per minute on what is called a spin table in the ...

The rare molecule weighing in on the birth of planets

Astronomers using one of the most advanced radio telescopes have discovered a rare molecule in the dust and gas disc around a young star—and it may provide an answer to one of the conundrums facing astronomers.

Saturn's rings shine in Hubble's latest portrait

Saturn is so beautiful that astronomers cannot resist using the Hubble Space Telescope to take yearly snapshots of the ringed world when it is at its closest distance to Earth.

First 'overtones' heard in the ringing of a black hole

When two black holes collide, they merge into one bigger black hole and ring like a struck bell, sending out ripples in space and time called gravitational waves. Embedded in these gravitational waves are specific frequencies, ...

First Earth observation satellite with AI ready for launch

A few months from now will see the launch of the first European satellite to demonstrate how onboard artificial intelligence can improve the efficiency of sending Earth observation data back to Earth. Dubbed ɸ-Sat, or PhiSat, ...

A new journey into Earth for space exploration

Six astronauts, five space agencies and a fresh start into underground worlds to help prepare for living on other planets. ESA's latest training adventure will equip an international crew with skills to explore uncharted ...

Image: Avalanche season on Mars

Every spring, the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose.

First water detected on potentially 'habitable' planet

K2-18b, which is eight times the mass of Earth, is now the only planet orbiting a star outside the Solar System, or 'exoplanet', known to have both water and temperatures that could support life.
