Astronomers capitalize on early access to James Webb Space Telescope data
Write a comment
First in line to receive data transmissions from the James Webb Space Telescope, a team of astronomers at the University of California, Irvine and other institutions is using the unprecedentedly clear observations to reveal the secret inner workings of galaxies.
In a paper published in The Astrophysical Journal Letters, the researchers describe their examination of the nearby galaxy NGC 74 Webb draws back curtain on universe's early galaxies

A few days after officially starting science operations, NASA's James Webb Space Telescope propelled astronomers into a realm of early galaxies, previously hidden beyond the grasp of all other telescopes until now.
"Everything we see is new. Webb is showing us that there's a very rich universe beyond what we imagined," said Tommaso Treu of the University of California at Los Angeles, princ Webb observations point to a shorter cosmic dark age

The first galaxies may have formed far earlier than previously thought, according to observations from the James Webb Space Telescope that are reshaping astronomers' understanding of the early universe.
Researchers using the powerful observatory have now published papers in the journal Astrophysical Journal Letters, documenting two exceptionally bright, exceptionally distant galaxies, based Massive Volcanism May Have Altered Ancient Venus' Climate

Volcanic activity lasting hundreds to thousands of centuries and erupting massive amounts of material may have helped transform Venus from a temperate and wet world to the acidic hothouse it is today, a NASA paper suggests.
The paper also discusses these "large igneous provinces" in Earth's history which caused several mass extinctions on our own planet millions of years ago.

November 16, 2022, was a big day for all space industry fans. Artemis I, a first mission to the Moon after a break that lasted over 53 years, is finally launched. And while the eyes of millions were directed towards their screens to see the launch, only some people recognize the contributions of different countries to this achievement of humanity. In particular, the scientific contribution of Uk Perseverance investigates intriguing Martian bedrock

NASA's Perseverance Mars rover has begun exploring an area the science team calls "Yori Pass" near the base of Jezero Crater's ancient river delta. They've been eager to explore the region for several months after spotting a rock similar to one Perseverance collected samples from in July.

The first privately developed Indian rocket lifted off into the upper reaches of the atmosphere on Friday, in another milestone in the country's push to become a major space power.
The half-tonne Vikram-S rocket launched before midday local time and travelled in an arc, live footage from the Indian Space Research Organisation (ISRO) showed.

Mars is called the red planet. But once, it was actually blue and covered in water, bringing us closer to finding out if Mars had ever harboured life.
Most researchers agree that there has been water on Mars, but just how much water is still debated.
Now a study from the University of Copenhagen shows that some 4.5 billion years ago, there was enough water for the entire planet to be Scroll through the universe with a new interactive map

A new map of the universe displays for the first time the span of the entire known cosmos with pinpoint accuracy and sweeping beauty.
Created by Johns Hopkins University astronomers with data mined over two decades by the Sloan Digital Sky Survey, the map allows the public to experience data previously only accessible to scientists.
The interactive map, which depicts the actual position and real colors of 200,000 galaxies, is available online, where it can also be downloaded for free.
"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," says map creator Brice Ménard, a professor at Johns Hopkins.
"Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists.
Artemis 1 is off—and we're a step closer to using moon dirt for construction in space

NASA has just launched its first rocket in the Artemis program, which will, among other things, take scientific experiments to produce metal on the moon.
In recent years, a number of businesses and organizations have ramped up efforts to establish technologies on the moon. But doing work in space is expensive. Sending just one kilogram of material to the moon can cost US$1.2 million (A$1.89 million).
What if we could save money by using the resources that are already there? This process is called in-situ resource utilization, and it's exactly what astrometallurgy researchers are trying to achieve.
Why the moon?
The moon has amazing potential for future space exploration. Its gravity is only one-sixth as strong as Earth's, which makes it much easier to fly things from the moon to Earth's orbit than to fly them direct from Earth! And in an industry where every kilogram costs a fortune, the ability to save money is extremely attractive.
