In the vacuum of space, you cannot see an asteroid unless sunlight reflects off of its surface (its albedo). A 6-foot rock made of dark, carbon-rich or metallic material reflects almost no light against the pitch-black backdrop of space. 



'45,000 MPH blindspot': Why NASA failed to detect Northeast Ohio's 250-ton TNT Meteor before it hit Earth

Meteors strike the Earth's atmosphere daily, but they are almost entirely invisible during the day. For a meteor to be visible against a bright blue morning sky, as this one was at 8:57 a.m, it must be overwhelmingly luminous and incredibly powerful. 



'We can't defend': Why Cleveland Ohio meteor hit is a serious wake-up call for humanity

A meteorite that Earth three billion years ago might have set up the platform for life to thrive on the planet, a team of scientists has found. But not before causing massive devastation first.&nbsp;

The meteorite was first discovered in 2014 and was 200 times bigger than the asteroid that killed the dinosaurs 66 million years ago. Earth was covered by mainly oceans at this time with only a few continents jutting out from here and there. The impact generated a lot of heat that boiled the oceans and caused the biggest tsunami in the history of mankind.

The team drove and hiked to Eastern Barberton Greenbelt in South Africa three times to collect rocks and learn more about the impact. The region is one of the oldest places on Earth where signs of a meteorite crash can be seen.

Meteorite S2 was one of the several pieces of debris swirling around in space after Earth formed. Bigger than the asteroid killer, S2 was 40-60km wide with a mass 50-200 times greater. In comparison, the asteroid responsible for the extinction of dinosaurs was around 10 km wide, about the size of Mount Everest.

“We know that after Earth first formed there was still a lot of debris flying around space that would be smashing into Earth,” says Prof Nadja Drabon from Harvard University, lead author of the new research.

“But now we have found that life was really resilient in the wake of some of these giant impacts and that it actually bloomed and thrived,” she says.

At the time, Earth harboured simple life forms with microorganisms composed of single cells living on the planet.&nbsp;

Prof Drabon and her team looked for tiny fragments of rock that the impact left behind. They carried back hundreds of kilograms of rock to their lab for analysis.&nbsp;

They have now reconstructed the incident which they say made a 500km crater and pulverised rocks. Moving at fast speeds, the rocks formed a cloud around the globe.

“Imagine a rain cloud, but instead of water droplets coming down, it's like molten rock droplets raining out of the sky,” says Prof Drabon.

It triggered a tsunami that ripped up the sea floor, with heat boiling the oceans and evaporating tens of metres of water. Air temperatures increased by up to 100 degrees Celsius, the skies turned black which even sunlight could not penetrate. Simple life relying on photosynthesis was wiped out.

Surprisingly, the devastation churned up nutrients like phosphorus and iron, leading life to bounce back quickly and thrive.&nbsp;

“Life was not only resilient but actually bounced back really quickly and thrived,” Prof Drabon says.

Iron-rich water from the depths came up to the surface because of the tsunami which gave early microbes extra energy. Prof Drabon says that this finding cements the belief that early life received ample help from other rocks that struck Earth in its early years.

Life blossomed on infant Earth after massive meteorite strike billions of years ago

NASA's latest asteroid alert is about an aeroplane-sized space rock hurtling towards Earth at a speed of 73,055 km/hr. The space agency has released a list of asteroids that will come close to our planet in the next 8-9 days. The biggest of these is the 220-foot (67 metre) asteroid named 2024 NF. It will make its closest approach to Earth on July 17.&nbsp;

<h2>Does it pose a danger to Earth?</h2>

As per NASA, only those space bodies that make an approach as close as 4.6 million miles and are bigger than 150 metres&nbsp;in size pose a danger. However, since asteroid 2024 NF is only about 67 metres in size, it is not going to cause any damage. Notably, the asteroid will come as close as three million miles, as per NASA's Jet Propulsion Laboratory data.&nbsp;

NASA regularly keeps an eye out for near-Earth objects that can pose a danger. There are four more asteroids that are going to come close to Earth in the coming days. But their sheer size means that they will not cause any harm.&nbsp;

Asteroid 2024 BY15 is approaching Earth on July 16 and will be 3.85 million miles from Earth at its closest point.&nbsp;

Asteroid 2024 NJ3 will be extremely close to Earth at 762,000 miles on July 17, but it is merely 47 feet in length.&nbsp;

On July 21, another asteroid will fly close by. Asteroid 2024 MG1, 55 metres in length, will be 2.64 million miles away from Earth.&nbsp;

<h2>Why does NASA monitor asteroids?</h2>

Asteroids have the ability to cause major destruction to planets. The space agency regularly keeps an eye on near-Earth objects which can be classified as hazardous based on criteria. Besides protecting the planet against any impending doom, monitoring asteroids also lets NASA study these celestial visitors. By learning about their movement and travel patterns, scientists can devise ways to create safety plans for the future in case a potentially hazardous asteroid threatens Earth.&nbsp;

The DART is one such mission which aims to destroy an asteroid in the event of it becoming a threat to our planet. As part of the mission, scientists hit an asteroid to better understand how an asteroid can be deflected in the future. The DART mission broke the asteroid into several pieces, many of which are likely to hit Mars.&nbsp;

Asteroid 2024 NF hurtling towards Earth will come extremely close on this date

NASA has said that there are currently four asteroids that are coming towards Earth with frightening speed. Some of them are travelling&nbsp;at the speed of hypersonic ballistic missiles, but few of them will not hit the earth and go flying past it, as reported by NASA.&nbsp;

Asteroids are basically the minor planets of the inner solar system and have rocky, icy, or metallic bodies with no atmosphere. Though most of the&nbsp;asteroids look the same, their shapes and size vary significantly, ranging from 1 million rocks to a dwarf planet of almost 1000km in diameter. One such&nbsp;asteroid has already been seen flying over Earth&nbsp;in Canada recently.

Here is the information about four&nbsp;asteroids barrelling toward earth:&nbsp;

<h2>1. Asteroid 2005 LW3</h2>

This is the largest asteroid of them all and also the first one to be discovered by NASA. NASA's Planetary Defense Coordination Office has issued an&nbsp;alert against this huge asteroid named Asteroid 2005 LW3. It will make its closest approach to Earth on 23 November at a distance of just 1.1 million kilometres away from earth. This asteroid is colossal with its size ranging anywhere between 426 feet to 918 feet. NASA has warned that the space rock is already&nbsp;on its way toward the planet, travelling at the speed of 48580 kilometres per hour.

<h2>2. Asteroid 2022 WS2</h2>

This asteroid was red-flagged by NASA due to its extremely close approach to earth. The asteroid, with a size ranging between 39 feet and 88 feet, will be making its closest approach to Earth on 23rd November as well. It will be at a distance of 3 million kilometres from Earth, travelling&nbsp;at a speed of 42039 kilometres per hour.&nbsp;

<h2>3. Asteroid 2022 WR2</h2>

This other asteroid will also come extremely close to Earth on 23rd November. Its close approach will bring it within just 3.5 kilometres of Earth. The asteroid is already on its way toward Earth, travelling at an astounding speed of 27629 kilometres per hour. Fortunately, this asteroid is quite small and will not be of harm&nbsp;even if it hits the Earth.&nbsp;

<h2>4. Asteroid 2022 WL2&nbsp;</h2>

This is this week's fourth asteroid that might hit the surface of the earth. It has a size ranging between 29 feet and 65 feet. It will make its closest appearance to Earth on 23rd November, at a distance of 2.2 million kilometres. It is coming down towards earth with a lightening speed of 28980 kilometres per hour, which is twice the speed of a hypersonic ballistic missile.

Four dangerous asteroids whirling towards earth that might hit today, tells NASA

In a recent report, American space agency NASA has revealed that planet earth may actually face massive destruction in the year of 2036, by an asteroid strike.

According to NASA, the asteroid named Apophis will collide with Earth and it will have result in human extinction.

The asteroid was detected in 2004 by NASA and since then NASA has been observing the celestial body for the past 13 years, finally concluding that the deadly strike may occur in 2036.

The news has been confirmed by Duane Brown, a NASA official at the Washinton Headquarters. Reported by IB Times.

Steve Chesley, a NASA scientist, along with his fellow teammate Paul Khodas from the jet propulsion laboratory of NASA, learned the about the asteroid since 2009, and they have predicted the collision to precisely occur on April 13, 2036.

Dave Tholen and his collaborators at the University of Hawaii&#39;s Institue for astronomy made the observations and confirmed about the updated orbit of Apophis&nbsp;

&quot;Apophis was one of those heavenly bodies, which attracted the interest of the public, as it was discovered in 2004. Updated computational techniques and newly available data indicate the probability of collision of the Earth April 13, 2036,&quot; writes NASA on its website.

Russians scientists have also claimed that asteroid Apophis will have a close flyby in 2029 at a distance of 32,000 km&nbsp;from&nbsp;Earth, and during this time, even a small deviation in its trajectory will cause mass destruction.

Earlier the conspiracy theorists predicted the end of the world to be on November 19, 2017, following a strike by Nibiru or Planet X. However, it was turned out to be a failure.

According to David Meade, another conspiracy theorist, doomsday has already been triggered as of October 15, 2017. He also said that the world will witness seven-year tribulation period through a series of natural disasters including earthquakes, tsunamis, and volcanic eruptions. Meade also claimed that Nibiru has already approached the Earth&#39;s orbit
