Planetary Defense Coordination Office Planetary Defense at NASA Near-Earth objects (NEOs) are asteroids and comets that orbit the Sun like the planets, but their orbits can bring them into Earth’s neighborhood – within 30 million miles of Earth’s orbit. Planetary defense is “applied planetary science” to address the NEO impact hazard. NASA established the Planetary Defense Coordination Office (PDCO) to manage its ongoing mission of planetary defense. The PDCO: Provides early detection of potentially hazardous objects (PHOs) – the subset of NEOs whose orbits predict they will come within 5 million miles of Earth’s orbit; and of a size large […]

5 ways to stop an asteroid from crashing into Earth Noel Wong @ FMT Lifestyle June 30, 2022 7:00 AM Imagine this if you will: Tomorrow, you read the news to find that sea levels are still rising as are food prices. Oh, and a world-ending asteroid is headed straight for Earth. As unlikely as an asteroid impact is right now, asteroids are very real and have changed the face of the Earth at least once. After all, it was an asteroid that singlehandedly wiped out the dinosaurs 66 million years ago, paving the way for the “Jurassic Park” films. […]

  NASA PUBLISHES THE RESULTS OF ITS INTENSE KILLER ASTEROID DRESS REHEARSAL MATT WILLIAMS AND UNIVERSE TODAY 6.13.2022 4:00 AM  The lessons learned could help avert real impacts in the near future or significantly limit the devastation one could cause. IN AND around our planet, there are thousands of comets and asteroids known as near-Earth objects (NEOs). Multiple space agencies and government affiliates are responsible for tracking them, especially those known as potentially hazardous asteroids (PHA). These objects are so-designated because they will cross Earth’s orbit and may even collide with it someday. Considering how impacts in the past have caused mass extinctions (like the Chicxulub impact event that […]


Science Voice: Bringer of chaos By Terry Mejdrich Freelance writer & former science teacher Apr 24, 2022 In ancient Egypt, Apophis was a mythological deity and the enemy of the sun god, Ra.  The deity was sometimes referred to as the Great Serpent. The sun was thought to be like a flaming ship or barge that Ra rode across the sky every day.  Ra represented life and light; Apophis represented darkness and chaos.  Every night when Ra descended into the underworld he would have to battle with Apophis and win in order to rise again in the next day. Apophis and Ra died with […]

  Unexpected Asteroid Smacks into Earth With Little Warning – Should We Be Concerned? 03-18-2022 Talia Wise An asteroid took astronomers by surprise recently, hitting Earth’s atmosphere just two hours after it was first detected by scientists. Thankfully, the stone wasn’t big enough to cause a major catastrophe on Earth. The refrigerator-sized cosmic rock, named 2022 EB5, is only the fifth asteroid spotted right before hitting the planet and is the first sighting of its kind since 2019. Last week, astronomer Krisztian Sarneczky noticed the asteroid while viewing space from the Piszkéstető Mountain Station in Northern Hungary. Sarneczky reported the […]

Asteroid Hits Off the Coast of Iceland, Becoming the Fifth Known Earth Impactor By Louise Franco Mar 16, 2022 12:58 AM EDT An asteroid has potentially struck off the coast of Iceland, as per the latest reports. Astronomers only detected the asteroid two hours before it entered the Earth’s atmosphere and crashed near the waters of Iceland on Friday, March 11. Known as asteroid 2022 EB5, the three-meter space rock is considered to be the “fifth known Earth impactor” on record. However, it is not clear whether the asteroid hit the waters off Iceland or dissipated upon entering the atmosphere, as per WUSA9 news. Yet, […]

This ‘Space Shotgun’ Could Destroy Asteroids Hours Before They Hit The Earth Jannat Un NisaMarch 11, 2022 Asteroids may present a major risk to Earth, and therefore, NASA is working on a technology that may kill a space rock hours before it collides with the Earth. Scientists may now check the skies for potentially dangerous asteroids. Nearly 28,000 objects close to the Earth have been discovered by NASA’s Near-Earth Object Observations (NEOO) Program. This, however, is not enough. There should be a mechanism to defend ourselves if we identify a dangerous asteroid hanging over our heads. Fortunately, NASA’s Dart mission is on its […]

Near Earth Objects Cover-Up What’s Wrong with NEOWISE Nathan Myhrvold In a 2016 preprint and two papers published online in December 2017 titled “Asteroid thermal modeling in the presence of reflected sunlight” and June 2018, “An empirical examination of WISE/NEOWISE asteroid analysis and results” in the journal Icarus, I raised a number of scientific, methodological, and ethical problems with the NEOWISE asteroid research project and its published papers and results. In this article, I summarize the problems in a less formal way than the papers, and I explain how the scientific misconduct that I found can be verified by anyone. Unlike a formal research paper I […]

What Are Potentially Hazardous Asteroids and Is an Asteroid Predicted to Hit Earth? BY ROBERT LEA ON 1/13/22 AT 5:40 AM EST An asteroid over twice the size of the Empire State Building will make a close approach to Earth on January 18. The asteroid, 7482 (1994 PC1), will pass within around 1.2 million miles of Earth. This means that the asteroid is both close enough and large enough, with a diameter of around 1,000 meters, to be defined as a Potentially Hazardous Asteroid (PHA)by NASA‘s Center of Near-Earth Object Studies (CNEOS). This is despite the fact that there is no risk of 7482 (1994 […]

‘Potentially hazardous’ asteroid bigger than Empire State Building to pass Earth by: Darcie Loreno, Nexstar Media Wire Posted: Jan 12, 2022 / 04:07 PM PST / Updated: Jan 12, 2022 / 04:07 PM PST (WJW) — An asteroid that’s more than twice the height of the Empire State Building is set to pass Earth next week. The asteroid, which NASA calls (7842) 1994 PC1, was actually first discovered in 1994. According to NASA’s Jet Propulsion Laboratory, it’s about 3,280 feet in diameter and is moving at 43,754 miles per hour. While it will be close to Earth, it will safely pass even though NASA is categorizing the asteroid as “potentially […]

(Photo : MasterTux on Pixabay) Gigantic Asteroid Will Pass By Earth in 7 Years, Do We Have Defense Against Such Threats? By Rain Jordan Jan 07, 2022 11:23 PM EST A minor chance of striking Earth in 2068 was supposed to exist for the near-Earth asteroid, but radar measurements have ruled that out. Asteroid 99942 Apophis was recognized as one of the most dangerous asteroids that might hit Earth after its detection in 2004. As astronomers followed Apophis and its orbit became more known, that impact assessment altered. According to the findings of a new radar monitoring campaign combined with accurate orbit analysis, […]
