“It could completely reshape our understanding of the solar system and of other planetary systems, and how we fit into that context. Brown and his colleague, planetary scientist Konstantin Batygin, reported having strong evidence of a hidden planet on the fringes of our solar system. “If you look at these bodies, their lifetimes are tiny compared to the age of the solar system,” Batygin said. “By now, we expected to have found many more of these extreme trans-Neptunian objects,” Sheppard said in an email. Finding a smaller planet would also spark excitement, Rice added, because every solar system planet is immensely useful for extrapolating information about the thousands of comparable exoplanets that researchers are uncovering across the galaxy.

☆ Crater offers new clue near-Earth asteroid is really a piece of the moon, scientists say

The space rock, known as 2016 HO3, is a rare quasi-satellite — a type of near-Earth asteroid that orbits the sun but sticks close to our planet. Astronomers first discovered it in 2016 using the Pan-STARRS telescope, or Panoramic Survey Telescope and Rapid Response System, in Hawaii. Scientists call the asteroid Kamo’oalewa, a name derived from a Hawaiian creation chant that alludes to an offspring traveling on its own. Kamo’oalewa specimen: A connecting puzzle pieceStudying crater impacts on the moon can also help scientists better understand the consequences of asteroid impacts should a space rock pose a threat to Earth in the future. There’s no other place, no other planet in our solar system with a moon like our moon.

☆ ‘Old smoker’ stars revealed at the heart of the Milky Way

CNN —A decade-long survey of the night sky has revealed a mysterious new type of star astronomers are referring to as an “old smoker.”These previously hidden stellar objects are aging, giant stars located near the heart of the Milky Way galaxy. This illustration shows an eruption occurring in the swirling disk of matter around a newborn star. They help the newborn star in the middle to grow, but make it harder for planets to form. Infrared images show a red giant star, located 30,000 light years away near the center of the Milky Way. Understanding how the old smokers release elements into space could change the way astronomers think about the way such elements are distributed across the universe.

☆ Eerie image shows spectacular aftermath of a large star's death

Oct 31 (Reuters) - The aftermath of a large star's explosive death is seen in an image released on Monday by the European Southern Observatory, showing immense filaments of brightly shining gas that was blasted into space during the supernova. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). The image shows the supernova remnants about 11,000 years after the explosion, Leibundgut said. The beauty of such images is that we can directly see what material was inside a star," Leibundgut added. The star itself has been reduced in the aftermath of the supernova to an incredibly dense spinning object called a pulsar.

☆ NASA awards SpaceX a $255 million contract to launch the next space telescope, which will study dark energy and exoplanets

Elon Musk's SpaceX will launch the Nancy Grace Roman Space Telescope in 2026 under a new NASA contract. The telescope will study dark energy, dark matter, galaxies, and exoplanets, NASA said. The Nancy Grace Roman Space Telescope, which is 2.4 meters in diameter, is slated to launch in October 2026, the space agency said in a press release. Under the contract, SpaceX will launch the telescope on a Falcon Heavy rocket from NASA's Kennedy Space Center in Florida. According to NASA, the Roman telescope will launch on a Falcon Heavy rocket, which SpaceX bills as "the world's most powerful rocket."
