☆ Voyager 2’s defining Uranus flyby may have been skewed by a rare cosmic event
▼ + stars: | 2024-11-11 | by ( Ashley Strickland | ) edition.cnn.com time to read: +7 min

Magnetospheres are the protective bubbles around planets like Earth that have magnetic cores and magnetic fields, and they are driven by the planet’s magnetic field. Voyager 2’s data showed that Uranus’ magnetosphere was home to unexpectedly powerful electron radiation belts. Voyager 2’s observations of Uranus’ magnetosphere defied the way astronomers understand how magnetic fields trap energetic particles and their radiation. The first panel (left) of this artist's concept depicts how Uranus' protective magnetosphere behaved prior to Voyager 2's flyby. Fortunately, sending a dedicated mission to study Uranus in the future has become a priority for NASA, according to a report released in 2022.

In this case, filaments radiate away from a “zombie star” the explosion created. Then, in 2023, astronomers spied weird filaments glowing with light from sulfur within the nebula. Scientists know the supernova created the filaments, but it’s unclear how or when the structures formed. The robust data that the instrument captured allowed the team to measure the motions of each filament and create a 3D map. The Keck Cosmic Web Imager enabled measurements of the velocity of any material within the nebula that emits light.

One of Euclid’s primary goals is to observe dark matter and dark energy. While dark matter has never been detected, it is believed to make up 85% of the total matter in the universe. Meanwhile, dark energy is a mysterious force thought to play a role in the accelerating expansion of the universe. Rhodes is the US science lead for Euclid and principal investigator for NASA’s Euclid dark energy science team. “The images capture detail from clusters of stars near an individual galaxy to some of the largest structures in the universe.

CNN —New observations of Jupiter’s Great Red Spot captured by the Hubble Space Telescope show that the 190-year-old storm wiggles like gelatin and shape-shifts like a squeezed stress ball. Although storms are generally considered unstable, the Great Red Spot has persisted for nearly two centuries. Recently, a separate team of astronomers peered into the heart of the Great Red Spot using the James Webb Space Telescope to capture new details in infrared light. The Great Red Spot seems to wiggle like a bowl of gelatin over the 90-day period.

Its owner, Brigitte Kruse, formed a relationship with Elvis' ex-wife, Priscilla Presley, and has even acted as her power of attorney. The questions over some of Kruse’s Elvis items reflect the murky world of celebrity memorabilia. The problem, these collectors say, is that there are dishonest people with Elvis ties providing bogus items to auction houses. In her suit, Priscilla said they were introduced by a mutual connection who said Kruse wanted to discuss her business selling Elvis memorabilia. In the days before the auction, Priscilla did media interviews explaining why she was endorsing it.

☆ Unusual world offers astronomers a glimpse into how planets become ‘hot Jupiters’
▼ + stars: | 2024-07-17 | by ( Ashley Strickland | ) edition.cnn.com time to read: +9 min

The star is one of a binary pair, so the planet orbits the primary star, while the primary star orbits a secondary star. While Jupiter takes 4,000 Earth days to complete one orbit around the sun, hot Jupiters complete one orbit every few days. Astronomers use “eccentric” to refer to the shape of a planet’s orbit on a scale from zero to 1. “It’s a pretty extreme process in that the changes to the planet’s orbit are massive,” Millholland said. Discovering a second hot Jupiter precursor is helping astronomers to confirm the idea that high-mass gas giants transform into hot Jupiters as they migrate from eccentric to circular orbits, the researchers said.

☆ Piping Up at the Gates of Dawn

Since the James Webb Space Telescope began operating two years ago, astronomers have been using it to leapfrog one another millions of years into the past, back toward the moment they call cosmic dawn, when the first stars and galaxies were formed. Last month, an international team doing research as the JWST Advanced Deep Extragalactic Survey, or JADES, said it had identified the earliest, most distant galaxy yet found — a banana-shaped blob of color measuring 1,600 light-years across. It was already shining with intense starlight when the universe was in its relative infancy, at only 290 million years old, the astronomers said. The new galaxy, known as JADES-GS-z14-0, is one of a string of Webb discoveries, including early galaxies and black holes, that challenge conventional models of how the first stars and galaxies formed. “This discovery proves that luminous galaxies were already in place 300 million years after the Big Bang and are more common than what was expected,” the researchers wrote in a paper posted to an online physics archive.

Now, a new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that’s attracting scrutiny and alternate theories. If Dyson spheres really exist, what could they be used for? “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare. “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. However, he added, the radiation fingerprint of the seven Dyson sphere candidates might be explained by natural phenomena as well.

CNN —The Hubble Space Telescope will transition to a new way of operating that aims to prevent the space observatory from experiencing lapses in its ability to observe the universe, according to NASA officials. The storied telescope, which has captured breathtaking images of the cosmos for 34 years, has traditionally operated using six gyroscopes. NASA's Hubble Space Telescope eyes the universe in May 2009 after one of the space shuttle missions to service the space observatory. Hubble is expected to operate into the mid-2030s, with its cosmic observations providing a complement to the work of the James Webb Space Telescope and future observatories that haven’t launched yet, Clampin said. “We do not see Hubble as being on its last legs,” Crouse said, “and we think it’s a very capable observatory.”

CNN —Two teams of scientists have discovered a theoretically habitable planet, smaller than Earth but bigger than Venus, orbiting a small star about 40 light-years away. Working on the assumption that the exoplanet doesn’t have an atmosphere, scientists calculated its surface temperature to be around 107 degrees Fahrenheit (42 degrees Celsius). Once temperate Earth-size planets have been identified, scientists can then analyze them to determine which elements are contained in their atmospheres and, crucially, whether water is present to sustain life. This method involves capturing starlight that shines through an exoplanet’s atmosphere and seeing which wavelengths are absorbed by certain molecules, revealing their presence in the atmosphere. As well as shedding light on the exoplanet itself, Palethorpe said scientists are hoping that this work can help us understand our own planet better.

An international coalition of astronomers has newly discovered an unusual planet, dubbed WASP-193b, that’s about 50% bigger than Jupiter and somehow still the second lightest planet ever found. Because of how small the mass signal was, it took the team four years to gather data and calculate WASP-193b’s mass, Barkaoui explained. Eventually the team discovered the planet’s mass is a measly 14% that of Jupiter, despite being so much bigger. But a bigger size means a bigger “extended atmosphere,” said study coauthor Julien de Wit, an associate professor of planetary science at MIT. “WASP-193b is an outlier of all planets discovered to date,” he said.

The nebula, 3,400 light-years away in the Perseus constellation, is an expanding shell of gases kicked out by a dying red giant star. Before the aging red giant star collapsed, it released a ring of gas and dust. The companion star, once in orbit around the red giant, is nowhere to be seen in Hubble’s image. Since collapsing, the red giant star has transformed into a dead stellar remnant known as an ultra-dense white dwarf star. “The space telescope is the most scientifically productive space astrophysics mission in NASA history,” according to a NASA release.
