Getting the thick and thin on the Milky-Way's evolution

The Milky Way may have evolved in different phases, beginning with the formation of disk stellar populations about thirteen billion years ago, scientists suggest.

Astronomers map the movement of white dwarfs of the Milky Way

White dwarfs were once normal stars similar to the Sun but then collapsed after exhausting all their fuel. These interstellar remnants have historically been difficult to study. However, a recent study reveals new information about the movement patterns of these puzzling stars.

Study analyses the characteristics of Apophis, the asteroid that will approach Earth in 2029

The Apophis asteroid was discovered in 2004 and has been monitored since then due to its classification as a potentially hazardous asteroid (PHA), as it was estimated that it would have a 2% chance of hitting Earth.

Space-grown lettuce could help astronauts avoid bone loss

Scientists report transgenic lettuce that produces a bone-stimulating hormone. Someday, astronauts could grow the lettuce in space and help guard against bone loss - simply by eating a big bowl of salad.

Astronomers reveal best image yet of mysterious ORCs in space

We now have the clearest image of the latest mysterious object in our known universe, odd radio circles (or ORCs). ORCs are so faint, rare and far away, that it takes the world's most advanced radio telescopes to find and describe them.

Cosmic flashes pinpointed to a surprising location in space

The location matched exactly with a dense cluster of very old stars, known as a globular cluster.

Three space station studies helping scientists understand the early universe

Research conducted aboard the International Space Station is helping scientists answer questions about the formation of the universe and origins of life on Earth.

Theoretical model explains how dust grains can grow into the seeds of new planets

By amassing in high-density regions, dust grains avoid drifting toward the star they are orbiting.

Ensuring the performance of microelectronics in space (w/video)

Researchers have developed advanced microelectronics that are resistant to harsh radiation in space and other environments. The microelectronics were tested with a high energy microprobe technology that can simulate the effects of space radiation.

Moon's orbit proposed as a gravitational wave detector

Scientists propose using the variations in distance between the Earth and the Moon, which can be measured with a precision of less than a centimeter, as a new gravitational wave detector within a frequency range that current devices cannot detect.

Combing the cosmos: New color catalog aids hunt for life on frozen worlds

Aided by microbes found in the subarctic conditions of Canada's Hudson Bay, an international team of scientists has created the first color catalog of icy planet surface signatures to uncover the existence of life in the cosmos.

Comet 67P's abundant oxygen more of an illusion, new study suggests

A new study suggests the comet has two internal reservoirs that make it seem like there's more oxygen than is actually there.

Meteorites that helped form earth may have formed in the outer solar system

Evidence suggests surface minerals of outer main-belt asteroids, proposed to have sourced building blocks of Earth's water and life, are only stable at low temperatures. These asteroids formed in distant orbits and may help explain Earth's composition.

Scientists announce discovery of supermassive binary black holes

Astronomers have discovered a supermassive black hole binary system, one of only two known such systems. The two black holes, which orbit each other, likely weigh 100 million suns each.

'Bubble-through' nuclear engine might be a future NASA workhorse

A cutting-edge nuclear thermal propulsion rocket engine using what's called centrifugal liquid fuel bubble-through could one day be a ticket for NASA to go directly into deep space.

Cosmic particle accelerator at its limit

Gamma ray observatory H.E.S.S. reveals a cosmic particle acceleration process in unprecedented detail.

The new, improved Dragonfly is a galactic gas detector

The Dragonfly telescope is undergoing a metamorphosis. For the past decade, the Dragonfly Telephoto Array has conducted groundbreaking science by detecting faint starlight within dimly lit parts of the night sky. The telescope uses clusters of telephoto lenses to create images, much the way a dragonfly's eyes gather visual data. Now Dragonfly is setting its sights on extragalactic gas.

Imagining an Earthly neighbor

New modelling work provides deep insight into how an Earth-like planet orbiting the Sun-like stars closest to us, the ? Centauri A/B binary, would look like, should it exist.
