CNN —When NASA’s next-generation space observatory launches in a few years, the Nancy Grace Roman Space Telescope will expand the search for exoplanets as well as rogue planets, or worlds that travel through space without orbiting stars. Understanding these rogue planets could shed more light on the formation, evolution and disruption of planetary systems. This illustration shows what the Nancy Grace Roman Space Telescope will look like in orbit. But rogue planets are likely much smaller. Telescopes like Hubble and the James Webb Space Telescope have enabled astronomers to observe large, glowing gas giant exoplanets called hot Jupiters.

☆ NASA’s Webb telescope image shows details of Saturn
▼ + stars: | 2023-07-04 | by ( Kristen Rogers | ) edition.cnn.com time to read: +3 min

CNN —Astronomers have discovered surprising details about Saturn’s atmosphere, using a new image captured by NASA’s James Webb Space Telescope. In the image, Saturn itself appears extremely dark due to the near-total absorption of sunlight by methane gas. The image was taken with Webb’s Near-Infrared Camera, known as NIRCam, as part of a Webb program that involves several exceptionally deep exposures of Saturn, according to NASA. This latest detailed image comes just weeks after the Webb telescope spotted a record-breaking water plume erupting from Saturn’s moon Enceladus, which feeds Saturn’s diffuse E ring, according to NASA. In the future, additional and deeper exposures from Webb will help astronomers examine fainter rings around Saturn, according to NASA.

☆ An experiment that reaches across the galaxy has 'heard' an invisible sea of ripples in space-time for the first time. It's surprisingly loud.
▼ + stars: | 2023-06-30 | by ( Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +9 min

Those ripples are probably the distant thunder of countless collisions between supermassive black holes, throughout space and time. He predicted that the intense gravity of extremely massive objects, like black holes, warps the fabric of space-time. The NSF funded the 15-year experiment, which is called the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). Supermassive black holes are thought to exist at the center of every galaxy. Her lab runs computer models of merging supermassive black holes to predict how they behave and what signals they send out into space.

China Daily via REUTERSBEIJING, May 30 (Reuters) - China sent three astronauts to its now fully operational space station as part of crew rotation on Tuesday in the fifth manned mission to the Chinese space outpost since 2021, state media reported. The astronauts on Shenzhou-16 will replace the three-member crew of the Shenzhou-15, who arrived at the space station late in November. China has already announced plans to expand its permanently inhabited space outpost, with the next module slated to dock with the current T-shaped space station to create a cross-shaped structure. Leading the Shenzhou-16 mission was Jing Haipeng, 56, a senior spacecraft pilot from China's first batch of astronaut trainees in the late 1990s. Also by the end of 2023, China is due to a launch space telescope the size of a large bus.

☆ Webb telescope spies evidence of hidden planets around nearby star
▼ + stars: | 2023-05-08 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

The revelation of the Fomalhaut’s two inner rings has suggested that planets hidden deeper within the star system may be affecting the dust belt’s shape. Stars form from gas and dust, and then a ring of leftover material called a protoplanetary disk orbits the star, where planets are born. Once the planets form around a star, debris belts form and become shaped by the gravity of the planets. Studying the dust belts can help unlock more of the secrets behind how planetary systems form. “I think it’s not a very big leap to say there’s probably a really interesting planetary system around the star.”

☆ Webb telescope captures glowing starburst as galaxies collide

CNN —A brilliant starburst feature shines in the latest image taken by the James Webb Space Telescope. The space observatory captured a bright burst of star formation triggered by two spiral galaxies crashing into one another. The colliding galaxies, known collectively as Arp 220, generated an infrared glow that contains the light of more than 1 trillion suns. This brilliant luminosity creates the diffraction spikes, or starburst feature witnessed by Webb. The new Webb image also reveals tails, or material streaming away from the galaxies due to gravity, in blue, to indicate activity as the galaxies continue to collide.

The discovery is another example of how observations by Webb, which was launched in 2021 and began collecting data last year, are transforming our knowledge of the nature of the early universe. The orbiting infrared observatory was designed to be far more sensitive than its Hubble Space Telescope predecessor. This galaxy, Kelly said, is "absolutely tiny" in relative terms. "Nonetheless, we found that it was forming about two stars each year, which is similar to the rate at which the Milky Way is forming stars," Kelly added. "The combined power of the James Webb Space Telescope and the galaxy's magnification due to gravitational lensing allows us to study this galaxy in detail," Williams said.

Our solar system was hit by a gamma-ray burst so bright, it blinded space equipment and telescopes. A gamma-ray burst that recently hit our solar system was so bright, it temporarily blinded gamma-ray instruments in space, according to a NASA release. Scientists say the gamma-ray burst (GRB), the most powerful type of explosion in the universe, was 70 times brighter than any previously recorded event. What is a gamma-ray burst? Because it blinded space instruments, they couldn't accurately record it, so scientists weren't sure how bright the burst was when it first reached our planet.

A NASA Hubble image may show the first runaway supermassive black hole ever discovered. Astrophysicists have long theorized that black holes could "go rogue" or "run away," if other black holes pushed them out of their galaxies. But nobody has ever confirmed a black hole wandering through intergalactic space, much less a supermassive black hole going rogue. And while two galaxies colliding is the simplest explanation for a rogue black hole, that's not what seems to have happened here. Even though they're invisible, there's no reason to worry about rogue supermassive black holes sneaking up on us from other galaxies.
