James Webb telescope captures images of possible newly discovered exoplanet
NASA's James Webb Space Telescope has captured evidence of a planet beyond the solar system for the first time since its launch in 2021.
The exoplanet, a planet beyond our solar system, has been dubbed TWA 7b and orbits the young nearby star TWA 7, NASA said. Scientists believe the exoplanet is around the mass of Saturn and is about 50 times the distance of Earth from the Sun, according to NASA.
Usually, planets of this size outside of our solar system are difficult to detect, but scientists used a technique called high-contrast imaging to detect the exoplanet, NASA said. Images of the exoplanet were taken using a coronagraph, which allows researchers to suppress the bright glare of a star to reveal faint nearby objects.
Scientists said there was a very small chance the images could show a background galaxy, but evidence "strongly points to the source being a previously undiscovered planet."
"Our observations reveal a strong candidate for a planet shaping the structure of the TWA 7 debris disk, and its position is exactly where we expected to find a planet of this mass," said lead researcher Anne-Marie Lagrange.
The exoplanet could be a young and cold planet with a mass around 0.3 times that of Jupiter and a temperature near 120 degrees Fahrenheit, according to initial analysis from researchers.
The first time scientists discovered an exoplanet was back in 1992. Astronomers have discovered nearly 6,000 exoplanets since then, but none of them are known to be habitable.

Rare Jupiter-sized planet discovered 3,200 light-years away using Einstein's space-time warping method
Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 light-years from Earth in the galactic bulge. It takes AT2021uey b 4,170 days to orbit its dwarf star, according to a study published in the journal Astronomy & Astrophysics. Advertisement According to Live Scence, AT2021uey b's shadow was first spotted in 2021 in data taken by the European Space Agency's Gaia telescope. It took the astronomers multiple check-ins to confirm the details of the planet. The astronomers discovered the planet using microlensing, a method used only three times previously, according to the study. Microlensing, which is based on Einstein's theory of relativity, relies on massive objects moving through the galaxy to warp the fabric of the universe, called space-time.

ESA/ATG medialab / SWNS Dr. Marius Maskoliunas, astronomer at Vilnius University and co-author of the study, discussed in a statement posted in just how much work goes into using this method. 'This kind of work requires a lot of expertise, patience and, frankly, a bit of luck. You have to wait for a long time for the source star and the lensing object to align and then check an enormous amount of data,' Maskoliunas said in the statement. 'Ninety percent of observed stars pulsate for various other reasons, and only a minority of cases show the microlensing effect.' 3 A visualization of the Milky Way and Andromeda galaxies. NASA/ESA et al. / SWNS Advertisement According to the study, microlensing occurs when a massive celestial body briefly positions itself directly in front of an even more distant star. As the planet settles in front of the star during its journey, the light begins to curve around the planet, magnifying the light of the star. According to the study, this temporary magnified light is what astronomers are searching for. Maskoliunas gave an example of how to imagine how microlensing works. 3 An illustration depicts NASA's Juno spacecraft in orbit above Jupiter.

You don't see the bird itself and don't know what color it is — only its shadow,' Maskoliunas said in the statement. 'But from it, you can, with some level of probability, determine whether it was a sparrow or a swan and at what distance from us. It's an incredibly intriguing process.' According to Live Science, there have been nearly 6,000 planets discovered since 1992 using two other more common practices known as transmit photometry and radial velocity. These more common practices will detect planets through host stars becoming dimmer due to said planets. They will also detect the wobble of the planets' gravitational pulls that occur.

‘Scary' Fireball Seen Shooting Across the Sky Confirmed as Meteor That Exploded with the Force of 20 Tons of TNT: See the Video
Witnesses across southeastern U.S. states reported seeing a 'really scary' fireball moving across the sky on June 26 A NASA expert confirmed to PEOPLE that the object was a meteor, which is a streak of light caused by a small space rock burning up after entering Earth's atmosphere 'It disintegrated 27 miles above West Forest, Georgia, unleashing an energy of about 20 tons of TNT,' NASA saidThe 'scary' fireball that witnesses saw shooting across the sky in southeastern U.S. states on Thursday, June 26, has been identified. Bill Cooke, NASA's Meteoroid Environment Office lead, confirmed to PEOPLE that the moving object was a meteor — a streak of light caused by a small space rock burning up after entering Earth's atmosphere. 'The meteor was first seen at an altitude of 48 miles above the town of Oxford, Georgia, moving southwest at 30,000 miles per hour,' Cooke said in a statement, adding that his team analyzed eyewitness accounts and camera, satellite, infrasound and doppler weather radar data. 'It disintegrated 27 miles above West Forest, Georgia, unleashing an energy of about 20 tons of TNT. The resulting pressure wave propagated to the ground, creating booms heard by many in that area,' Cooke continued. He added in the statement that the meteor was produced by an asteroidal fragment that was 3 feet in diameter and weighed more than a ton. CBS Mornings reported that at least 20 fireball events have been tracked worldwide in 2025, per NASA's Center for Near Earth Objects Studies. Georgia resident Melanie Whitlock told Atlanta news station WSB-TV that feeling the meteor's sonic boom 'was really, really scary.'

SpaceX launches second mission in 2 days from same pad, breaks own record
June 28 (UPI) -- SpaceX early Saturday launched another 27 Starlink satellites, breaking its own record by preparing the launchpad for another liftoff two days after a launch from the same pad in Florida. And 13 hours later, the private company launched more satellites from California. Saturday's first mission went off from Cape Canaveral Space Launch Complex 40 at 12:26 a.m. EDT. This was just two days, eight hours, 31 minutes and 10 seconds after the launch of a Starlink mission from the same pad, besting a previous SpaceX record set in March by 28 minutes. Watch Falcon 9 launch 27 @Starlink satellites to orbit from Florida SpaceX (@SpaceX) June 28, 2025 SpaceX also uses a pad at nearby Kennedy Space Station. The launch occurred despite inclement weather that passed through Florida's Space Coast on Friday night. The first stage flew for a fifth time, which has included Starlink missions. About eight minutes after liftoff, the booster landed on the droneship "A Shortfall of Gravitas" stationed in the Atlantic Ocean. This was the 115th landing on the drone ship and 469th booster landing since, according to Spaceflight now. The first droneship landing was on April 8, 2016, on "Of Course I Still Love You" in the Atlantic, which is used in the Pacific Ocean. Ten years ago on June 28, a Falcon 9 that launched from the Cape Canaveral site broke apart in an explosion during a NASA resupply mission to the International Space Station. The first Falcon 9 launch was five years earlier on June 4, 2010, from Cape Canaveral. Launch from California SpaceX launched another 26 Starlink satellites from Vandenberg Space Launch Complex 4 East in California. The Falcon 9 lifted off at 1:13 p.m. PDT. It was the eighth flight for the first-stage booster supporting this mission, including three Starlink missions. The first stage then landed on the "Of Course I Still Love You" droneship. It's the 139th touchdown on this vessel. Watch Falcon 9 launch 26 @Starlink satellites to orbit from California SpaceX (@SpaceX) June 28, 2025
