Chandra rewinds story of Great Eruption of the 1840s
A new movie made from over two decades of data from NASA's Chandra X-ray Observatory shows a famous star system changing with time, as described in our latest press release. Eta Carinae contains two massive stars (one is about 90 times the mass of the Sun and the other is believed to be about 30 times the Sun's mass).
In the middle of the 19th century, skywatchers observed as Eta Carinae e Heating and cooling space habitats isn't easy
China, India and the U.S. have all achieved landing on the Moon in the 2020s.
Once there, their eventual goal is to set up a base. But a successful base - along with the spacecraft that will carry people to it - must be habitable for humans. And a big part of creating a habitable base is making sure the heating and cooling systems work.
That's especially true because the ambient temp ISS National Lab and Privateer announce Data and Information Sharing Partnership
The International Space Station (ISS) National Laboratory and Privateer Space, a leader in space decision intelligence and data infrastructure, announced a partnership to bring additional resources to the growing space economy. The announcement was made during a session at the annual ISS Research and Development Conference (ISSRDC) focused on companies innovating within the space landscape. Study sheds new light on strange lava worlds
Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system.
To date, nearly 50% of all rocky exoplanets yet discovered have been found capable of maintaining magma on their surfaces, likely because these planets are so close to their host stars they orbit in fewer than 10 days. Being so close Alien Machines in the Solar System: The Possibilities and Potential Origins
In 2018, the scientists Adam Frank and Gavin Schmidt proposed the Silurian hypothesis. It considered the potential of finding ancient evidence in Earth's geologic record that a non-human industrial civilization could exist on Earth millions of years ago. But could any outcomes of the technogenic activities of such a civilization survive until present day? Irina K. Romanovskaya, who is a graduate Possible hints of life found on distant planet - how excited should we be?
Data from the James Webb Space Telescope (JWST) has shown that an exoplanet around a star in the constellation Leo has some of the chemical markers that, on Earth, are associated with living organisms. But these are vague indications. So how likely is it that this exoplanet harbours alien life?
Exoplanets are worlds that orbit stars other than the Sun. The planet in question is named K2-18 JWST's first spectrum of a TRAPPIST-1 planet
In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star. Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how its star can affect observations of exoplanets in the habitable zone of cool s The OSIRIS-REx sample canister lid is removed
NASA scientists found black dust and debris on the avionics deck of the OSIRIS-REx science canister when the initial lid was removed today. The canister from the OSIRIS-REx sample return capsule was delivered to NASA's Johnson Space Center in Houston on Sept. 25 after landing in the Utah desert on Sept. 24.
Johnson houses the world's largest collection of astromaterials, and curation exper Likely asteroid debris found upon opening of returned NASA probe
After a seven-year wait, NASA scientists on Tuesday finally pried open a space probe carrying the largest asteroid samples ever brought back to Earth, finding black debris.
Researchers "found black dust and debris on the avionics deck of the OSIRIS-REx science canister when the initial lid was removed today," the US space agency said, though without specifying whether they definitely belonged to the asteroid.
Scientists are eagerly awaiting researching the bulk of the sample, which will require "intricate disassembly" of the probe.
OSIRIS-REx launched in 2016, landing on the asteroid Bennu and collected roughly nine ounces (250 grams) of dust from its rocky surface.
Even that small amount, NASA has said, should "help us better understand the types of asteroids that could threaten Earth."
It ended its 3.86-billion-mile (6.21-billion-kilometer) journey after touching down in the desert in the western state of Utah on Sunday, following a high-stakes, fiery descent through Earth's atmosphere.
Listening to the radio on the far side of the moon
There are unexplored regions of the universe—and there are also unexplored times. In fact, there's a nearly 400-million-year gap in our universe's history that we've never seen: a time before stars known as the Dark Ages. To investigate that era, researchers want to pick up a particular radio signal that can't be measured from Earth.
The first step to listening for it is a pathfinder project known as the Lunar Surface Electromagnetics Experiment-Night, or LuSEE-Night. The experiment is slated to head to the moon in 2025, where it will test technology in the harsh lunar environment.
The project is a collaboration between NASA and the Department of Energy, with partners from Lawrence Berkeley National Laboratory (Berkeley Lab), Brookhaven National Laboratory (lead DOE lab), UC Berkeley, and the University of Minnesota.
