Sea ice is a critical indicator of changes in the Earth's climate. A new discovery by Brown University researchers could provide scientists a new way to reconstruct sea ice abundance and distribution information from the ancient past, which could aid in understanding human-induced climate change happening now. In a study published in Nature Communications, the researchers show that an orga

Astronomers refer to observations as "deep" when they are taken with very long exposure times. Just as with photography, this gathers more light, revealing distant, fainter objects. Deeper exposures let astronomers look deeper into the Universe - hence the name. This particular deep image was taken with a 70-minute exposure with the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Obse

NASA's upcoming space telescope, the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, or SPHEREx, is one step closer to launch. The mission has officially entered Phase C, in NASA lingo. That means the agency has approved preliminary design plans for the observatory, and work can begin on creating a final, detailed design, as well as on building the ha

A secret behind the workings of sunquakes - seismic activity on the Sun during solar flares - might be hidden beneath the solar surface. These earthquake-like events release acoustic energy in the form of waves that ripple along the Sun's surface, like waves on a lake, in the minutes following a solar flare - an outburst of light, energy, and material seen in the Sun's outer atmosphere.

From a mountain high in Chile's Atacama Desert, astronomers with the National Science Foundation's Atacama Cosmology Telescope (ACT) have taken a fresh look at the oldest light in the universe. Their new observations plus a bit of cosmic geometry suggest that the universe is 13.77 billion years old, give or take 40 million years. The new estimate matches the one provided by the standard mo

China's Tianwen 1 robotic Mars probe had traveled more than 400 million kilometers by Sunday morning and is set to enter a Mars orbit next month, according to the China National Space Administration. By 6 am Sunday, the spacecraft had flown for 163 days on an Earth-Mars transfer trajectory and was about 8.3 million km from the red planet, the administration said in a statement, adding that

NASA is targeting the final test in the Green Run series, the hot fire, for as early as Jan.17. The hot fire is the culmination of the Green Run test series, an eight-part test campaign that gradually brings the core stage of the Space Launch System (SLS) - the deep space rocket that will power the agency's next-generation human Moon missions - to life for the first time. NASA conducted th

China's Mars probe Tianwen-1 has traveled more than 400 million km by Sunday morning and is expected to enter Mars orbit next month, according to the China National Space Administration (CNSA). As of 6 a.m. on Sunday (Beijing Time), the Mars probe had flown in space for 163 days. It was about 130 million km from Earth and about 8.3 million km from Mars. According to the CNSA, the pro

Exolaunch, the leading rideshare launch and deployment services provider for the NewSpace industry, begins its launch campaign to integrate 30 small satellites from the U.S. and Europe aboard SpaceX's Falcon 9 rideshare mission scheduled for no earlier than January 2021. This is the first dedicated rideshare mission of SpaceX's SmallSat Rideshare Program and the first of several rideshares

China Aerospace Science and Technology Corp, the country's leading space contractor, says it plans to launch more than 40 missions this year, including some for the nation's space station program. In a report read at the State-owned conglomerate's annual space programs meeting on Monday in Beijing, the company said the most important missions in 2021 will be sending the space station's maj
