“On November 8, one hundred percent of the round disk of the full Moon slowly moves into the dark shadow, and the bright Moon grows dim. The Moon does not, however, become completely dark,” the observatory wrote in an event description. Instead, it usually glows with a copper or red color, a result of sunlight being filtered and bent through the Earth’s atmosphere (much like a sunset).”
The Griffith Observatory will not be open to in-person viewing of the lunar eclipse, but will offer a time-lapse video of the event on its YouTube page at about 11 a.m. EST (8 a.m. PST, 1600 GMT).
How lunar eclipses occur and when’s the next one
Total lunar eclipses occur when the moon passes behind Earth with respect to sun. This sends the moon into Earth’s shadow, blocking the sunlight that typically illuminates the moon as seen from Earth’s surface.
Since the moon’s orbit around Earth as a tilt, it doesn’t pass through the darkest part of Earth’s shadow, called the umbra, every month. When it passes through only part of Earth’s shadow, it creates a partial lunar eclipse. During a total lunar eclipse, the entire moon is in Earth’s shadow, turning it a blood-red color with light that is refracted through Earth’s atmosphere.
According to NASA, a total lunar eclipse occurs every 1.5 years or so, but multiple ones can occur in a year. The Nov. 8 blood moon is the second total lunar eclipse of 2022 and follows the Super Flower Blood Moon eclipse in May.
The next total lunar eclipse after Nov. 8 will be on March 13, 2025. There will be a second total lunar eclipse that year as well, on Sept. 7, 2025, according to NASA’s eclipse website. In 2023 and 2024, the moon will experience either partial lunar eclipse, when only part of the moon passes through the umbra, or an ever-so-slight penumbral eclipse, when the moon dips through the outermost layer of Earth’s shadow, called the penumbra.

James Webb Space Telescope finds water in super-hot exoplanet's atmosphere – Space.com
The James Webb Space Telescope has found traces of water vapor in the atmosphere of a super-hot gas giant exoplanet that orbits its star in less than one Earth day.
The exoplanet in question, WASP-18 b, is a gas giant 10 times more massive than the solar system‘s largest planet, Jupiter. The planet is quite extreme, as it orbits the sun-like star WASP-18, which is located some 400 light-years away from Earth, at an average distance of just 1.9 million miles (3.1 million kilometers). For comparison, the solar system’s innermost planet, Mercury, circles the sun at a distance of 39.4 million miles (63.4 million km).
Due to such close proximity to the parent star, the temperatures in WASP-18 b’s atmosphere are so high that most water molecules break apart, NASA said in a statement. The fact that Webb managed to resolve signatures of the residual water is a testament to the telescope’s observing powers.

“The spectrum of the planet’s atmosphere clearly shows multiple small but precisely measured water features, present despite the extreme temperatures of almost 5,000 degrees Fahrenheit (2,700 degrees Celsius),” NASA wrote in the statement. “It’s so hot that it would tear most water molecules apart, so still seeing its presence speaks to Webb’s extraordinary sensitivity to detect remaining water.”
WASP-18 b, discovered in 2008, has been studied by other telescopes, including the Hubble Space Telescope, NASA’s X-ray space telescope Chandra, the exoplanet hunter TESS and the now-retired infrared Spitzer Space Telescope. None of these space telescopes, however, was sensitive enough to see the signatures of water in the planet’s atmosphere.
“Because the water features in this spectrum are so subtle, they were difficult to identify in previous observations,” Anjali Piette, a postdoctoral fellow at the Carnegie Institution for Science and one of the authors of the new research, said in the statement. “That made it really exciting to finally see water features with these JWST observations.”
In addition to being so massive, hot and close to its parent star, WASP-18 b is also tidally locked. That means one side of the planet constantly faces the star, just like the moon‘s near side always faces Earth. As a result of this tidal locking, considerable differences in temperature exist across the planet’s surface. The Webb measurements, for the first time, enabled scientists to map these differences in detail.
The measurements found that the most intensely illuminated parts of the planet can be up to 2,000 degrees F (1,100 degrees C) hotter than those in the twilight zone. The scientists didn’t expect such significant temperature differences and now think that there must be some not yet understood mechanism in action that prevents the distribution of heat around the planet’s globe.
“The brightness map of WASP-18 b shows a lack of east-west winds that is best matched by models with atmospheric drag,” co-author Ryan Challener, of the University of Michigan, said in the statement. “One possible explanation is that this planet has a strong magnetic field, which would be an exciting discovery!”
To create the temperature map, the researchers calculated the planet’s infrared glow by measuring the difference in the glow of the parent star during the time the planet transited in front of the star’s disk and then when it disappeared behind it.
“JWST is giving us the sensitivity to make much more detailed maps of hot giant planets like WASP-18 b than ever before,” Megan Mansfield, a Sagan Fellow at the University of Arizona and one of the authors of the paper describing the results. said in the statement. “This is the first time a planet has been mapped with JWST, and it’s really exciting to see that some of what our models predicted, such as a sharp drop in temperature away from the point on the planet directly facing the star, is actually seen in the data.”
The new study was published online Wednesday (May 31) in the journal Nature.
JWST Scans an Ultra-Hot Jupiter's Atmosphere – Universe Today
When astronomers discovered WASP-18b in 2009, they uncovered one of the most unusual planets ever found. It’s ten times as massive as Jupiter is, it’s tidally locked to its Sun-like star, and it completes an orbit in less than one Earth day, about 23 hours.
Now astronomers have pointed the JWST and its powerful NIRSS instrument at the ultra-Hot Jupiter and mapped its extraordinary atmosphere.
Ever since its discovery, astronomers have been keenly interested in WASP-18b. For one thing, it’s massive. At ten times more massive than Jupiter, the planet is nearing brown dwarf territory. It’s also extremely hot, with its dayside temperature exceeding 2750 C (4900 F.) Not only that, but it’s likely to spiral to its doom and collide with its star sometime in the next one million years.

For these reasons and more, astronomers are practically obsessed with it. They’ve made extensive efforts to map the exoplanet’s atmosphere and uncover its details with the Hubble and the Spitzer. But those space telescopes, as powerful as they are, were unable to collect data detailed enough to reveal the atmosphere’s properties conclusively.
Now that the JWST is in full swing, it was inevitable that someone’s request to point it at WASP-18b would be granted. Who in the Astronomocracy would say no?
In new research, a team led by a Ph.D. student at the University of Montreal mapped WASP-19b’s atmosphere with the JWST. They used the NIRISS instrument, one of Canada’s contributions to the JWST. The paper is “A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b.” It’s published in Nature, and the lead author is Louis-Philippe Coulombe.
The researchers trained Webb’s NIRISS (Near-Infrared Imager and Slitless Spectrograph) on the planet during a secondary eclipse. This is when the planet passes behind its star and emerges on the other side. The instrument measures the light from the star and the planet, then during the eclipse, they deduct the star’s light, giving a measurement of the planet’s spectrum. The NIRISS’ power gave the researchers a detailed map of the planet’s atmosphere.
With the help of NIRISS, the researchers mapped the temperature gradients on the planet’s dayside. They found that the planet is much cooler near the terminator line: about 1,000 degrees cooler than the hottest point of the planet directly facing the star. That shows that winds are unable to spread heat efficiently to the planet’s nightside. What’s stopping that from happening?
“JWST is giving us the sensitivity to make much more detailed maps of hot giant planets like WASP-18 b than ever before. This is the first time a planet has been mapped with JWST, and it’s really exciting to see that some of what our models predicted, such as a sharp drop in temperature away from the point on the planet directly facing the star, is actually seen in the data!” said paper co-author Megan Mansfield, a Sagan Fellow at the University of Arizona.
The lack of winds moving the atmosphere around and regulating the temperature is surprising, and atmospheric drag has something to do with it.
“The brightness map of WASP-18 b shows a lack of east-west winds that is best matched by models with atmospheric drag,” said co-author Ryan Challener, a post-doctoral researcher at the University of Michigan. “One possible explanation is that this planet has a strong magnetic field, which would be an exciting discovery!”
In our Solar System, Jupiter has the strongest magnetic field. Scientists think that swirling conducting materials deep inside the planet, near its bizarre liquid, metallic hydrogen core generates the magnetic fields. The fields are so powerful that they protect the three Galilean moons from the solar wind. They also generate permanent aurorae and create powerful radiation belts around the giant planet.
But WASP-18 b is ten times more massive than Jupiter, and it’s reasonable to think its magnetic fields are even more dominant. If the planet’s magnetic field is responsible for the lack of east-west winds, it could be forcing the winds to move over the North Pole and down the South Pole.
The researchers were also able to measure the atmosphere’s temperature at different depths. Temperatures increased with altitude, sometimes by hundreds of degrees. They also found water vapour at different depths.
At 2,700 Celsius, the heat should tear most water molecules apart. The fact that the JWST was able to spot the remaining water speaks to its sensitivity.
“Because the water features in this spectrum are so subtle, they were difficult to identify in previous observations. That made it really exciting to finally see water features with these JWST observations,” said Anjali Piette, a postdoctoral fellow at the Carnegie Institution for Science and one of the authors of the new research.
But the JWST was able to reveal more about the star than just its temperature gradients and its water content. The researchers found that the atmosphere contains Vanadium Oxide, Titanium Oxide, and Hydride, a negative ion of hydrogen. Together, those chemicals could combine to give the atmosphere its opacity.
All these findings came from only six hours of observations with NIRISS. Six hours of JWST time is precious to astronomers, and that’s all the researchers needed. That’s not only because the JWST is so powerful and capable, but also because of WASP-18 b itself.
At only 400 light-years away, it’s relatively close in astronomical terms. Its proximity to its star also helped, and the planet is huddled right next to its star. Plus, WASP-18 b is huge. In fact, it’s one of the most massive planets accessible to atmospheric investigation.
The planet’s atmospheric properties also provide clues to its origins. Comparisons of metallicity and composition between planets and stars can help explain a planet’s history. WASP-18 b couldn’t have formed in its current location. It must have migrated there somehow. And while this work can’t answer that conclusively, it does tell us other things about the giant planet’s formation.
“By analyzing WASP-18 b’s spectrum, we not only learn about the various molecules that can be found in its atmosphere but also about the way it formed. We find from our observations that WASP-18 b’s composition is very similar to that of its star, meaning it most likely formed from the leftover gas that was present just after the star was born,” Coulombe said. “Those results are very valuable to get a clear picture of how strange planets like WASP-18 b, which have no counterpart in our Solar System, come to exist.”
Private astronaut crew, including first Arab woman in orbit, returns from space station – Indiatimes.com
An all-private astronaut team of two Americans and two Saudis, including the first Arab woman sent into orbit, splashed down safely off Florida on Tuesday night, capping an eight-day research mission aboard the International Space Station (ISS).
After spending 8 days on a space exploration mission, four astronauts, including two from the United States and the other two from Saudi Arabia, returned to Earth safely off the coast near Florida. Although the mission was funded by private entities, the mission included deep space exploration and was a landmark achievement in terms of the inclusion of women in this field.

The space crew came back in a SpaceX Dragon capsule, after completing 12 hours in the return journey. The space capsule is said to have descended in a very hot environment at blazing speeds through Earth’s atmosphere. The splashdown was carried live by a SpaceX and Axiom Space joint webcast.
Axiom Space spent millions of dollars off its own pocket to send a private expedition to the space station. The company organized, prepared and funded the mission that involved their second attempt to get into space, without any government intervention. Axiom Space is based in Houston and is run by a former NASA researcher, who had worked on the initiation of NASA’s International Space Station program.
Peggy Whitson, who is 63, led the Axiom 2 crew. She holds the record for most time spent in orbit with 665 days divided into 3 long space missions. This includes her 10 spacewalks. Along with her were John Shoffner, who is a professional race car driver and investor, and two astronauts from Saudi Arabia, who helmed cancer stem cell research, and were fighter pilots by profession.
Barnawi and Alqarni are two Saudi women who went to space just five years after Saudi Arabia removed restrictions on women driving. Sara Sabry was another woman from Egypt who went into space in 2022 for a short duration. At that time, Alqarni and Barnawi were on board the international space station with Sultan Alneydi from UAE. They made history as the triplets were the first three astronauts into space from Saudi Arabia.
