893-DarkSky Oregon Artificial light at night also known as light pollution is degrading human safety and health as well as damaging the natural environment on which we all depend. The loss of the connection with the natural night sky has happened over the past 100 years. Restoring the natural night sky is relatively simple and can even save money. Before restoration can effectively begin it is essential to make night sky brightness measurements in both natural night sky and urban locations.

Inside a bold plan to pulverize an Earth-bound asteroid It’s the stuff of movies: an asteroid is on a collision course with Earth, and we have to do something to stop it—or die. Disturbingly this scenario is also the stuff of the actual universe. Scientists have discovered more than 2,000 “potentially hazardous” asteroids. To merit that official NASA designation, an object must be at least 460 feet in diameter and have an orbit that passes within about 4.7 million miles of our planet. Protecting Earth from these rocky hazards falls under a field called “planetary defense.” A group of researchers at the University of California, Santa Barbara, has a deceptively simple idea for how to take care of such an asteroid: pulverize it.

Bennu Asteroid Samples Show Uneven Distribution of Organic Compounds and Minerals A recent study of samples collected from asteroid Bennu by NASA's OSIRIS-REx mission reveals that the asteroid's chemistry is highly heterogeneous. Scientists found that organic compounds and minerals are grouped into three distinct regions, each shaped by past interactions with liquid water. Using advanced nanoscale infrared and Raman spectroscopy techniques, researchers examined sample OREX-800066-3 at scales as small as 20 nanometers. The study identified regions rich in simple carbon-based molecules, carbonate minerals indicating past water activity, and nitrogen-containing organics critical for biological molecules. These findings suggest that water did not affect Bennu uniformly, resulting in a patchwork of chemical environments. Despite these interactions, fragile organic molecules remained intact, offering clues about how life's building blocks can survive in space. This research provides insights into the processes that shaped primitive asteroids, the early Solar System, and the potential delivery of life's ingredients to Earth.

382E-418-Fireball II Recently there were four fireball meteors, brighter than the planet Venus, which exploded over Germany, France, Ohio, and Arizona within the space of only 10 hours. A total of 1320 individuals were treated to light shows and reported their observations to the American Meteor Society. The one which exploded over Arizona was probably several feet in diameter and entered the Earth's atmosphere over Flagstaff. This event was observed in Arizona, California, Nevada, Utah, New Mexico, and Colorado. It was recorded by numerous electronic security and dashboard cameras and was visible for from 3 to 7 seconds. This meteor also produced a booming sound which was reported by about a dozen different observers. The fireball was last seen over Happy Jack, Arizona and is likely to have produced meteorite fragments which are scattered along Interstate 17 somewhere in the rugged country between Phoenix and Flagstaff. There are likely to be on the order of 1,000 fireball events over the Earth every day. Most of them occur over the oceans or during the day and pass unobserved by humans. During the first 10 months of 2017 the most energetic fireball event occurred when a meteoroid entered the Earth's atmosphere at 8.5 miles/second above the ocean between Australia and Antartica. If you record a fireball with your dash cam or security camera report it to the American Meteor Society. Your data will be very important in finding out where it came from in the solar system as well as to indicate where it might be possible to find pieces of it on the ground.

The asteroid #Pallas, the second to be discovered, was clearly identified on #ThisDayInHistory in 1802. German astronomer #HeinrichWMOlbers pinpointed the highly eccentric, high-inclination #asteroid that is likely a #protoplanet left over from the formation of our solar system.

We could protect Earth from dangerous asteroids using a huge magnet We could deflect potentially hazardous asteroids by using an enormous magnet to gently pull them apart. This idea avoids some of the pitfalls of the more traditional kinetic impactor method, which involves smashing something into an asteroid to move it, but it has yet to be tested, so we can’t be sure it would work. The idea is called non-contact orbital velocity adjustment, or NOVA, and Gunther Kletetschka at the University of Alaska Fairbanks presented it at the Lunar and Planetary Science Conference in Texas on 17 March. In his calculations, he applied the NOVA concept to an asteroid called 2024 YR4, which briefly seemed like it might be on a trajectory to hit Earth or the moon in 2032, although further observations showed that it will pass safely by. The asteroid is small, less than 70 metres across, so it would present a relatively simple target to shift. The spacecraft itself would consist of a large magnet made from a coil of superconducting wire, about 20 metres in diameter, powered by a nuclear fission reactor. Small boosters would control its orbit around the asteroid, keeping it about 10 to 15 metres from the rock, so the magnet could act...

892-140m-asteroids Humans can mitigate the damage done by the impact of an asteroid given a sufficient lead time. In 1998, the US Congress mandated NASA to detect and track 90% of the 1 km sized asteroids capable of effecting local mass destruction as well as global disruption of agriculture and other human activities. This goal has been accomplished. In 2005 Congress extended the mandate to require NASA to detect and track 90% of the 140-m asteroids capable of destroying a large metropolitan area.

Dedicated Amateur Beats All-Sky Surveys to Asteroid Discovery A recent discovery highlights how amateurs can still make asteroid discoveries in a brave new era of all-sky surveys. It’s getting tough for amateur astronomers to breakthrough with new discoveries. Gone is the era of the lone amateur on a windswept hill sketching a star field from night to the next, looking for an errant ‘star’ that has moved against the background field heralding a new star or comet. The modern era of all-sky surveys including Pan-STARRS, ATLAS and now the Vera C. Rubin Observatory has given amateur astronomers some stiff competition. But many amateurs have simply upped their game, and took their quest online. The ability to access remote observatories has really helped in this regard. One recent discovery highlights this growing trend. Amateur astronomer Filipp Romanov was able to nab the fast-moving asteroid 2026 CQ3 flitting through the constellation Leo last month on the night of February 15th, 2026. “I requested the imaging of 15 photos (with 60-second exposures on the 2-meter Liverpool Telescope) to confirm one of the Main Belt asteroids I had found.” Filipp told Universe Today. “When they were taken and I looked through them, I saw a fast-moving (about 18 arcseconds per minute) faint...

381E-417-Red Dwarf Planets Astronomers continue to be delighted when they discover an Earth sized planet. Scientists were thus very disappointed when the red dwarf star hosting the nearest such planet, Proxima b some 4.2 light years away, turns out to have the nasty habit of emitting bursts of radiation which are likely to sterilize and/or remove the atmospheres of it's family of planets. Recently, hope of finding a nearby Earth was rekindled when scientists at the European Southern observatory in Chile discovered a small planet circling what appears to be a quiet well behaved red dwarf star 11 light years from us. Astronomers are not yet sure that this newly discovered Earth sized planet lies within it's stars habitable zone where liquid water could exist on it's surface. Jumping the gun, ET enthusiasts have beamed a friendly message in the direction of another nearby red dwarf planet system. Their target the super Earth planet, GJ 273b is located some 12.4 light years away near the bright star Sirius in the constellation of Canis Major. At this distance a civilization on GJ 273b could have already received a picture of humanity by deciphering 'I love Lucy' and other TV signals it has been picking up for 50 years or so. The next generation of very large telescopes will allow astronomers to search for the presence of oxygen and other molecules which indicate the presence of life in the atmospheres of nearby worlds. In the mean time we have more reasons to be thankful for what we have here on planet Earth. For Travelers in the Night this is Dr. Al Grauer.
