Dean LomaxIn May 2020, Ruby Reynolds, then 11, and her father, Justin, were searching for fossils on a Somerset beach along the English coast when she spotted something unusual. And when it came to sheer size, the marine reptile likely rivaled the blue whale, currently the largest living animal.

Observations from the European Space Agency’s Cheops space telescope, or Characterising ExOplanet Satellite, detected a “glory effect” on WASP-76b, an ultra-hot exoplanet 637 light-years from Earth. Cheops captured data from WASP-76b as the planet passed in front of its star, making 23 observations over three years. But the glory effect is created as light moves through a narrow opening and bends, creating colorful, patterned rings. An artist's illustration shows the night-side view of the exoplanet WASP-76b, where iron rains down from the sky. Lueftinger said she believes that the James Webb Space Telescope or Ariel may be able to help prove the presence of the glory effect on WASP-76b.

And the planets, labeled b through g, revolve around the star in a celestial dance known as orbital resonance. For every six orbits completed by planet b, the closest planet to the star, the outermost planet g completes one. As planet c makes three revolutions around the star, planet d does two, and when planet e completes four orbits, planet f does three. Detecting a mysteryResearchers first took notice of the star system in 2020 when NASA’s Transiting Exoplanet Survey Satellite, or TESS, detected dips in the brightness of HD110067. “It shows us the pristine configuration of a planetary system that has survived untouched.”The discovery is the second time Cheops has helped reveal a planetary system with orbital resonance.

CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago. The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. The six found so far are roughly two to three times the size of Earth, but with densities closer to the gas giants in our own solar system. This solar system is unique because all six planets move similar to a perfectly synchronized symphony, scientists said. All solar systems, including our own, are thought to have started out like this one, according to the scientists.

CNN —A huge prehistoric structure in Ohio has become the 25th US landmark to be awarded a place on the UNESCO World Heritage List. Historic siteNational Archaeological Park Tak’alik Ab’aj in Guatemala has also been named a UNESCO World Heritage site. “This inscription on the World Heritage List highlights the important work of American archaeologists, who discovered here remains dating back 2,000 years, constituting one of the largest earthwork constructions in the world. J.B. Barret/DEAL Martinique/Courtesy UNESCO World Heritage Nomination OfficeEstablished in 1978, the World Heritage List has inscribed well over 1,000 sites of “outstanding universal value” in the more than four decades since then.

☆ The Milky Way's shiniest known planet has metal clouds that rain down titanium. Astronomers say it 'shouldn't exist.'
▼ + stars: | 2023-07-12 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +3 min

A planet five times the size of Earth was found to be the shiniest planet outside our solar system. This ultra-hot planet "shouldn't exist" as it is and could be a new class of planet altogether. This planet's hot metal atmosphere is defying astronomers' rules for how planets of this size should behave. Venus, the solar system's shiniest planet, reflects 75% of the sunlight. "We believe these metal clouds help the planet to survive" in these conditions said study author Sergio Hoyer of the Marseille Astrophysics Laboratory.

☆ Shiniest exoplanet ever found has reflective metal clouds

CNN —An ultrahot exoplanet that zips around its host star every 19 hours is the shiniest exoplanet ever discovered. The scorching world, dubbed planet LTT9779b, has reflective metallic clouds made of silicates and metals like titanium. An artist's illustration shows an exoplanet, called LTT9779b, orbiting its much larger host star. The side of the exoplanet that faces its host star likely reaches 3,632 degrees Fahrenheit (2,000 degrees Celsius). And LTT9779b is so piping hot that it shouldn’t have any clouds, even those made of metal or glass.

☆ Alien planet with metallic clouds resembles 'a giant mirror in space'

Venus, the brightest object in Earth's night sky besides the moon, is our solar system's most reflective object, enrobed in toxic sulfuric acid clouds. An atmosphere with water-based clouds, as on Earth, would have been blown away by solar radiation long ago. But they believe its clouds are metallic, a combination of titanium and silicate - the stuff that makes up most of the rocks in Earth's crust. "We even think that the clouds could condense into droplets, and have titanium rain falling in parts of the atmosphere," Jenkins said. More than 5,000 planets beyond our solar system - called exoplanets - have been discovered, many with traits vastly different than our solar system's eight planets.

☆ Scientists discover corridor in Great Pyramid of Giza

CAIRO, March 2 (Reuters) - Egyptian antiquities officials announced on Thursday the discovery of a hidden nine metre-long corridor behind the main entrance of the Great Pyramid of Giza that they said could lead to further findings. The find was made under the Scan Pyramids project that since 2015 has been using modern technology including scans and endoscopes to peer inside the pyramid, the last of the Seven Wonders of the Ancient World still standing. The unfinished corridor was likely built to relieve the weight of the pyramid on either the main entrance, seven metres below, or on another as yet undiscovered chamber or space, said Mostafa Waziri, head of Egypt's Supreme Council of Antiquities. The Great Pyramid was built as a monumental tomb around 2560 BC, during the reign of the Pharaoh Khufu, or Cheops. It stands at a height of 146 metres (479 feet), the tallest structure built by humankind until the Eiffel Tower in Paris in 1889.

2 story has been corrected to delete height comparison in paragraph 4)A hidden corridor nine metres (30 feet) long has been discovered close to the main entrance of the 4,500-year-old Great Pyramid of Giza, and this could lead to further findings, Egyptian antiquities officials said on Thursday. The Great Pyramid was constructed as a monumental tomb around 2560 BC during the reign of the Pharaoh Khufu, or Cheops, to a height of 146 metres (479 feet). [1/4] A hidden corridor inside the Great Pyramid of Giza that was discovered by researches from the the Scan Pyramids project by the Egyptian Tourism Ministry of Antiquities is seen in Giza, Egypt March 2, 2023. Scientists detected the corridor through cosmic-ray muon radiography, before retrieving images of it by feeding a 6mm-thick endoscope from Japan through a tiny joint in the pyramid's stones. In 2017, Scan Pyramids researchers announced the discovery of a void at least 30 metres long inside the Great Pyramid, the first major inner structure found since the 19th century.
