'Oumuamua likely came from a binary star system

New research finds that 'Oumuamua, the rocky object identified as the first confirmed interstellar asteroid, very likely came from a binary star system.

Measuring white dwarf masses with gravitational lensing

Measuring the mass of a celestial body is one of the most challenging tasks in observational astronomy. The most successful method uses binary systems because the orbital parameters of the system depend on the two masses. In the case...Show More Summary

Two sub-Jovian exoplanets orbiting bright stars discovered

Using NASA's prolonged Kepler mission, known as K2, astronomers have identified two new gas giant exoplanets. The newly found alien worlds, designated HD 89345 b and HD 286123 b, are warm, low-density sub-Jovian planets circling bright stars. The finding is detailed in a paper published March 9 on

The first SpaceX BFR should make orbital launches by 2020

Elon Musk has a reputation for pushing the envelop and making bold declarations. In 2002, he founded SpaceX with the intention of making spaceflight affordable through entirely reusable rockets. In April of 2014, his company achieved success with the first successful recovery of a Falcon 9 first stage. Show More Summary

Scientists detect radio echoes of a black hole feeding on a star

On Nov. 11, 2014, a global network of telescopes picked up signals from 300 million light years away that were created by a tidal disruption flare—an explosion of electromagnetic energy that occurs when a black hole rips apart a passing star. Show More Summary

Black holes aren't totally black, and other insights from Stephen Hawking's groundbreaking work

Mathematical physicist and cosmologist Stephen Hawking was best known for his work exploring the relationship between black holes and quantum physics. A black hole is the remnant of a dying supermassive star that's fallen into itself; these remnants contract to such a small size that gravity is so strong even light cannot escape from them.

These are the places that (most likely) host alien life

Not too cold, not too hot—the conditions for life are found not just on Earth, but on a handful of other places out in the universe.

NASA powers on new instrument staring at the Sun

NASA has powered on its latest space payload to continue long-term measurements of the Sun's incoming energy. Total and Spectral solar Irradiance Sensor (TSIS-1), installed on the International Space Station, became fully operational with all instruments collecting science data as of this March.

Rare metals on Mars and Earth implicate colossal impacts

New research has revealed that a giant impact on Mars more than four billion years ago would explain the unusual amount of "iron loving" elements in the Red Planet.

A massive telescope for seeing the invisible

Some of the universe's greatest mysteries could soon be resolved thanks to the Square Kilometre Array (SKA), a huge radio telescope that will be built in South Africa and Australia. Several EPFL labs are involved in this epic projec...

Send your name to the sun aboard NASA's Parker Solar Probe

NASA's Parker Solar Probe—designed, built and managed by the Johns Hopkins Applied Physics Laboratory—will launch in summer 2018 on a historic mission to the sun.

New technique uses AI to locate and count craters on the moon

A new technique developed by researchers at U of T Scarborough is using the same technology behind self-driving cars to measure the size and location of crater impacts on the moon.

Humans could live in volcanic tunnels on the moon

The SETI Institute has analysed images of our moon and pinpointed a possible home away from Earth.

Researchers find space radiation is increasingly more hazardous

It might sound like something from a science fiction plot – astronauts traveling into deep space being bombarded by cosmic rays – but radiation exposure is science fact. As future missions look to travel back to the moon or even to Mars,...Show More Summary

NASA, ATLAS to mature portable space communications technology

Portable ground antenna stations could transform NASA's space communications capabilities. With access to undeveloped regions, the mobile systems could bolster the return of spacecraft science, instrument health and other data to Ea...

Shoebox-sized cube satellite to study Earth's inner radiation belt

A NASA-funded cube satellite built and operated by CU Boulder researchers will study the inner radiation belt of Earth's magnetosphere, providing new insight into the energetic particles that can disrupt satellites and threaten spacewalking astronauts.

Scientists design conceptual asteroid deflector and evaluate it against massive potential threat

Lawrence Livermore National Laboratory (LLNL) scientists are part of a national planetary defense team that designed a conceptual spacecraft to deflect Earth-bound asteroids and evaluated whether it would be able to nudge a massive asteroid – which has a remote chance to hitting Earth in 2135 – off course.

Dawn reveals recent changes in Ceres' surface

Observations of Ceres have detected recent variations in its surface, revealing that the only dwarf planet in the inner solar system is a dynamic body that continues to evolve and change.
