How Did Dino-Era Birds Survive the Asteroid 'Apocalypse'?

  How Did Dino-Era Birds Survive the Asteroid 'Apocalypse'? Fossil spores and bird family trees suggest that deforestation was a key factor in determining who survived 66 million years ago.The long-standing question, then, is why certain birds lived while others died in the mass extinction event at the end of the Cretaceous period?

By Deborah Byrd in Earth | January 2, 2014. This is only the second time that astronomers spotted an asteroid before it struck Earth ’s atmosphere . The asteroid could have impacted Earth ’s atmosphere anywhere along this line.

Eric Allen observed asteroid 2008 TC3 as it approached its impact on Earth on October 7, 2008 at 01:32 and 01:42 UTC. The observations were partly for the thrill -- seeing an object in its last hours , before it met a fiery fate in Earth 's atmosphere -- but they also had a more important purpose: to

A small asteroid discovered Saturday morning, determined to head for Earth, impacted the planet's atmosphere just a few hours later, according to NASA.

The cosmic boulder, named asteroid 2018 LA (and previously listed as ZLAF9B2), was estimated to be only about 6 feet (2 meters) across. It was first spotted by the Catalina Sky Survey in Arizona.

"The discovery of asteroid 2018 LA is only the third time that an asteroid has been discovered to be on an impact trajectory," said Paul Chodas, manager of NASA's Center for Near-Earth Object Studies (CNEOS), in a statement. "It is also only the second time that the impact location was predicted well ahead of the event itself."

Surprise! Pluto Has Dunes Made of Methane 'Sand'

  Surprise! Pluto Has Dunes Made of Methane 'Sand' The tiny world shouldn’t have enough atmosphere to create wind-sculpted dunes. So what’s going on?The observation is startling, given that scientists thought Pluto’s tenuous atmosphere wasn’t necessarily robust enough to support the formation of dunes, which by most definitions are sculpted by wind.

A comet or asteroid tears through Earth 's atmosphere and smashes into the ground or ocean with enough force to destroy civilization. Scientists will probably spot the object before it hits us. The Earth had been in that same spot a mere six hours earlier.

For just the second time in history, an asteroid was discovered before it impacted the Earth . Objects that small generally disintegrate as they ram through the Earth ’s atmosphere at high speed, so there was never And of course this underscores how seriously we need to take asteroid impacts .

All three asteroids burned up in the atmosphere and caused no reported damage.

NEO watchers calculated that asteroid 2018 LA would enter the atmosphere somewhere over a corridor extending from Africa across the Indian Ocean to Papua New Guinea. 

The final moments of the asteroid's existence appear to have been caught Saturday evening from a webcam in South Africa in the below clip. Although it looks like the fireball impacts the ground, it is really just disappearing over the horizon. NASA says it disintegrated several miles over the surface as it lit up the sky. 

"This was a much smaller object than we are tasked to detect and warn about," said Lindley Johnson, planetary defense officer at NASA Headquarters. "However, this real-world event allows us to exercise our capabilities and gives some confidence our impact prediction models are adequate to respond to the potential impact of a larger object."

Naked-Eye Asteroid and More Can't-Miss Sky Events in June

  Naked-Eye Asteroid and More Can't-Miss Sky Events in June Planetary pairings, a super-bright asteroid, and the astronomical start of a new season offer plenty of reasons to look up this month.So dust of those binoculars, and turn your gaze toward the heavens.

The scientist says the asteroid is 370 metres in diametre, and could hit the Earth with an explosion 1,000 times greater than the 2013 impact of Chelyabinsk meteorite. The enormous space rock entered Earth 's atmosphere over the Russian city of Chelyabinsk

SCORES of giant asteroids are on course to hurtle close to Earth before the end of February An impact would still be catastrophic destroying cities and knocking out transport and communication networks. The next asteroid is hurtling through space at more than 30,000 miles per hour .

One such larger object was the asteroid that went completely undetected until it collided with the atmosphere over Russia in 2013, creating a shock wave that blew out thousands of windows in the town of Chelyabinsk, causing a number of minor injuries. 

How much it's worth freaking out over these undetected or late-detected asteroids is up for debate. The smallest asteroids like 2018 LA are the hardest to spot, but also the least likely to do any damage. That said, it can never hurt to have more telescopes and eyes pointed at the sky looking for the next space rock aiming to knock on our door ... or break it down.


Mystery object spotted over Washington state island, military denies missile launch .
A weather camera on an island in Washington state on Sunday captured a mystery object that appears to some to be a missile in ascent, Q13Fox.com reported. The object was spotted at 3:56 a.m. over Whidbey Island, where there is a naval air station. But a spokesman from NAS Whidbey Island said there are no missile capabilities at the base."There's a lot of speculation around here,” Tom Mills, the spokesman, said. "But it's definitely not a missile launch."A professor of Atmospheric Sciences at the University of Washington speculated that the object looks like a missile.
