This asteroid is one of the most likely to hit Earth. NASA Explains.

This asteroid is one of the most likely to hit Earth. Here’s what it means for our future. New ultraprecise measurements show that the asteroid Bennu has a higher chance than thought of impacting our planet sometime in the next 300 years, NASA says. For hundreds of millions of years, a top-shaped rubble pile called Bennu has orbited the sun in relative isolation. The asteroid, about a third of a mile wide at its equator, poses no immediate threat to our planet. But hundreds of years from now, there is a small chance that Bennu could slam into Earth. In … Continue reading This asteroid is one of the most likely to hit Earth. NASA Explains.

Space station detectors found the source of weird ‘blue jet’ lightning

A ‘blue bang’ sparks an unusual type of lightning in the upper atmosphere Scientists have finally gotten a clear view of the spark that sets off an exotic type of lightning called a blue jet. Blue jets zip upward from thunderclouds into the stratosphere, reaching altitudes up to about 50 kilometers in less than a second. Whereas ordinary lightning excites a medley of gases in the lower atmosphere to glow white, blue jets excite mostly stratospheric nitrogen to create their signature blue hue. Blue jets have been observed from the ground and aircraft for years, but it’s hard to tell … Continue reading Space station detectors found the source of weird ‘blue jet’ lightning

O UFOs, Where Art Thou?

Five reasons why sorting all of this out is so scientifically challenging Just before the release in June of the much-anticipated Pentagon report on unidentified aerial phenomena (UAP), I sat down to try to create a list of the greatest hurdles to UAPs’ scientific analysis. What I came up with were five major challenges that are described here, together with a cross-comparison with some of the statements made in the published government report. Although only nine pages long, that report turns out to be thorough, careful and scientifically accurate in that it fully expresses how little certainty can be drawn from the … Continue reading O UFOs, Where Art Thou?

If aliens call, what should we do? Scientists want your opinion.

The Search for Extraterrestrial Intelligence (SETI) has been growing in confidence and repute lately thanks to astronomer’s detections of habitable worlds and the private funding been poured into the enterprise. With renewed efforts afoot, it’s worth pausing for a moment and asking – well what do we do if we succeed? How should the scientists communicate their results? How will the public react? Social media in particular disrupts the conventional pattern of scientific announcements and poses some interesting challenges for SETI. In this video we perhaps end up asking more questions than answers, but let’s get into a discussion in … Continue reading If aliens call, what should we do? Scientists want your opinion.

Inspiration4, the first all-civilian spaceflight, is now in orbit

The SpaceX mission seeks to raise some $200 million dollars for St. Jude Children’s Research Hospital.  Inspiration4 / John Kraus Last night at 8:02 PM EDT, the crew of Inspiration 4 — the first all-civilian spaceflight — blasted off from historic Launch Complex 39A at NASA’s Kennedy Space Center. Tucked inside a SpaceX Crew Dragon capsule, which was lofted to orbit atop a SpaceX Falcon 9 rocket, are four fortunate astronauts: Sian Proctor, Hayley Arceneaux, Christopher Sembroski, and Jared Isaacman. The latter footed the bill for the trip. Unlike the recent suborbital spaceflights of billionaires carried out this summer by Blue … Continue reading Inspiration4, the first all-civilian spaceflight, is now in orbit

Jupiter’s volcanic moon Io is emitting strange radio waves and NASA’s Juno probe is listening

The Juno spacecraft has gotten a private radio show from Jupiter’s closest moon, the highly volcanic Io. NASA’s Juno spacecraft is “listening” in on radio emissions from Jupiter’s volcanic moon Io, allowing researchers to discover what triggers the strange radio waves.  Of all the planets in our solar system, Jupiter has the largest and most powerful magnetic field, which extends so far that some of the planet’s moons orbit within it. Because Io is closest to the planet, the moon is “caught in a gravitational tug-of-war” between Jupiter and two other large moons, according to NASA. These opposing pulls cause massive internal heat, which has led … Continue reading Jupiter’s volcanic moon Io is emitting strange radio waves and NASA’s Juno probe is listening

Habitable Planets That Received Our Radio Signals And May Know We’re Here

We have been broadcasting for over 100 years. Now a new 3D map of the galaxy reveals the stars these signals have reached that can also see Earth. (Credit: sdecoret/Shutterstock) When Guglielmo Marconi made the first “long-distance” radio broadcasts in 1895, his assistant tuned into from a less than a kilometer away. Marconi went on to develop the world’s first commercial radio system and, by the time of his death in 1937, radio signals were routinely used to communicate across the world. These broadcasts have also travelled into space, signaling to all who care to tune in, that humanity has … Continue reading Habitable Planets That Received Our Radio Signals And May Know We’re Here

Researchers Generate an Entire Virtual Universe and Make it Available for Download (if you Have 100 Terabytes of Free Hard Drive Space)

#Virtual #Universe Astronomy is a bit different from many sciences because you only have a sample size of 1. The cosmos contains everything we can observe, so astronomers can’t study multiple universes to see how our universe ticks. But they can create computer simulations of our universe. By tweaking different aspects of their simulation, astronomers can see how things such as dark matter and dark energy play a role in our universe. Now, if you are willing to spring for a fancy hard drive, you can keep one of these simulations in your pocket. The Uchuu simulation is the largest … Continue reading Researchers Generate an Entire Virtual Universe and Make it Available for Download (if you Have 100 Terabytes of Free Hard Drive Space)

One-kilometer-wide asteroid captured by radar observatory

NASA’s Goldstone 70-meter (230 foot) antenna captured radar imagery of asteroid 2016 AJ193 on Aug. 22, 2021 as it passed about 2.1 million miles (about 3.4 million kilometers) away from Earth. A gigantic asteroid that is considered potentially hazardous by NASA zipped past the Earth at a very high rate of speed. The asteroid, called 2016 AJ193, flew past the Earth at a velocity of 58,000 mph. It’s hard to imagine a speed that high; it equates to traveling about 16 miles every second. NASA estimates the asteroid is about 4800 feet wide, approximately four times as wide as the Empire … Continue reading One-kilometer-wide asteroid captured by radar observatory

NASA has too Many Spacecraft to Communicate With. Time to Build More Dishes

#NASA #Spacecraft #Communicate #Dish NASA is a sprawling organization that has to talk to everything from politicians in Washington DC to space probes that have left the solar system.  Discussions with the first might be as simple as a written letter for informal conversation, while the second requires a high-power network of ground-based antennas.  Known as the Deep Space Network (DSN) this series of antennas spread over three continents is the backbone of NASA’s communications with its various space probes. Now the DSN is in the process of implementing a well-deserved upgrade. Part of the reason for that upgrade is the sheer … Continue reading NASA has too Many Spacecraft to Communicate With.

Giant Comets Pose a Greater Threat to Earth Than Asteroids

Astronomers Say Giant Comets Pose a Greater Threat to Earth Than Asteroids A team of astronomers has identified giant comets as a greater threat to life on Earth than asteroids. The biggest difference between the two celestial bodies is their composition: comets are composed of ice, dust, and rock, whereas asteroids are made up of metals and rock – which is why comets leave a ‘tail’, as the ice within them gets vapourised by the Sun. That distinction might not mean much to the average resident of planet Earth, but another major difference between comets and asteroids is where they can be … Continue reading Giant Comets Pose a Greater Threat to Earth Than Asteroids

#mars #crater #AI It could analyze a photo of the Martian surface in just five seconds. NASA scientists need 40 minutes. If you’ve ever played one of those “spot the difference between these two photos” games, you have something in common with NASA scientists. To identify newly formed craters on Mars, they’ll spend about 40 minutes analyzing a single photo of the Martian surface taken by the Context Camera on NASA’s Mars Reconnaissance Orbiter (MRO), looking for a dark patch that wasn’t in earlier photos of the same location. If a scientist spots the signs of a crater in one … Continue reading AI discovers new craters on Mars in just five seconds

First Ever FRB That Repeats Every 16 Days Gets More Mysterious

What’s creating these unusual signals? And why does this one repeat itself? A photo shows the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project at night. (Image credit: CHIME FRB) One of the universe’s deep mysteries just got a lot stranger. Astrophysicists have discovered a clue that could help explain why, every once in a while, superfast bursts of radio waves flash across Earth from deep space. But the clue — a repeating 16-day pattern in one of the bursts, undermines one of the most popular theories for where the bursts are coming from. #FRB #fastradioburst #space #astronomy #CHIME Fast radio bursts (FRBs) have … Continue reading First Ever FRB That Repeats Every 16 Days Gets More Mysterious

A bad solar storm could cause an “Internet apocalypse”

#solarstorm #Internet #apocalypse #cme #sun #solarflare Undersea cables would be hit especially hard by a coronal mass ejection. Scientists have known for decades that an extreme solar storm, or coronal mass ejection, could damage electrical grids and potentially cause prolonged blackouts. The repercussions would be felt everywhere from global supply chains and transportation to Internet and GPS access. Less examined until now, though, is the impact such a solar emission could have on Internet infrastructure specifically. New research shows that the failures could be catastrophic, particularly for the undersea cables that underpin the global Internet. At the SIGCOMM 2021 data communication conference on Thursday, Sangeetha … Continue reading A bad solar storm could cause an “Internet apocalypse”
