For years, it has been known that the most likely cause of the extinction of dinosaurs was an asteroid impact. The most common theory behind the extinction is the Alvarez hypothesis, which claims that an asteroid struck Earth nearly 65 million years ago and wiped out entire species of dinosaurs. This theory is backed by some proof too as scientists have also discovered its impact crater, known as the Chicxulub crater, buried under the Yucatan Peninsula in Mexico. As per the hypothesis, the impact of the asteroid would have caused the formation of huge tidal waves and an impact crater almost 140 km wide. Lland material would have splattered into space, changing the Earth into a nuclear winter-like environment, ultimately leading to the demise of dinosaurs.

NASA has recently issued details about an asteroid designated as Asteroid 2023 TK15 that is expected to make its closest approach to Earth on October 20.

You may think asteroids are simply floating rocks in space and while it may seem so due to their appearance, it isn't quite the case. These space rocks can be classified into 3 types based on their structural composition. The most commonly found asteroids are S-type, which are made up of carbon-rich substances. On the other hand, S-type asteroids are made up mainly of silicate minerals and are less common. M-type asteroids are the least prevalent and they are primarily composed of metal. NASA recently sent out a mission to a metal-rich asteroid called 16 Psyche which is supposedly worth more than the whole planet's economy put together, at a staggering $10 quintillion!

Hazards like solar storms and asteroids constantly appear and pose threats to our planet. NASA diligently monitors Near-Earth Asteroids (NEAs) to safeguard our planet from potential impacts. When NASA's telescopes detect a new NEA, precise observations of its position in the sky are reported to the Minor Planet Center. Subsequently, the Center for Near-Earth Object Studies (CNEOS) utilizes this data to establish the most likely orbit of the asteroid around the Sun. To evaluate the risk of impact and the asteroid's orbit, NASA employs the innovative Sentry II system, featuring a unique algorithm. Sentry II strategically selects random points within the entire uncertainty region, enabling the program to pinpoint very low-probability impact scenarios. Recently, NASA has issued an alert concerning a colossal asteroid that is approaching Earth tomorrow:

Asteroids are abundant in space and as many as 1298148 have been discovered to date.

It was not a small rock either, as scientists later revealed it was nearly 200 feet wide, about 4 times the size of the Chelyabinsk asteroid that caused massive damage in Russia. It was at last found by the Asteroid Terrestrials-Impacts Last Alert System (ATLAS) observatory in South Africa on July 15.

On September 8, 2016, NASA launched a historic mission - the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx). It was launched to study a Potentially Hazardous Asteroid (PHA) called Bennu, which has a 1/2700 chance of impacting Earth between 2175 and 2195. After a 6-year journey that involved landing on the asteroid and collecting samples from its surface, the spacecraft finally returned the samples last month, after which they underwent a “nitrogen purge”. Today, NASA will finally open up the canister returned by the OSIRIS-REx spacecraft and show off the asteroid sample to the world in an event that will be live-streamed. You can watch it online here.

To discover, monitor and study asteroids in space, NASA has several space telescopes and ground-based observatories in place. These include the famous Hubble Space Telescope and the new James Webb Space Telescope. Moreover, spacecraft such as Dawn, OSIRIS-REx, and Hayabusa2 have also helped in studying these ancient space rocks. As of now, there are 1,298,210 known asteroids in space and while not all of them are dangerous, some of them can get knocked off their orbit due to interaction with a planet's gravitational field such as Jupiter, and head towards Earth for potential impact. Therefore, to remove the uncertainties around the asteroid's approach, it is imperative that we track them.

Did you know that artificial intelligence (AI) is aiding in the discovery and study of asteroids? After aiding various industries across sectors such as education, healthcare, engineering and more, AI could also potentially help protect Earth against asteroids. According to a study published by the University of Washington, an algorithm, named HelioLinc3D, helped researchers discover a potentially hazardous asteroid. Asteroid 2022 SF289, which is almost 600 feet wide, was discovered during the algorithm's test in Hawaii and has not been deemed as dangerous in the foreseeable future.

NASA has several space and ground-based telescopes in place to discover, track, and study asteroids. But if you're a budding astronomer, you can help the space agency too! NASA's new Daily Minor Planet Project allows astronomers and skywatchers to help discover new asteroids and track them in data sets. To capture asteroids, the Daily Minor Project uses the NASA-funded, University of Arizona-based Catalina Sky Survey which captures nearly 1000 images every night. Due to this volume, NASA scientists fall short of personnel to study these images. After looking at the image, you just have to click on a yes or a no button and add a comment if necessary, before moving on to the next image.

Asteroids often pass Earth at close distances, posing a threat to the planet with their terrifying approaches. Most of them might seem like they're just floating rocks in space, but did you know asteroids have differing compositions? These space rocks can be classified into 3 types based on their structural composition. The most commonly found asteroids are S-type, which are made up of carbon-rich substances. On the other hand, S-type asteroids are made up mainly of silicate minerals and are less common. M-type asteroids are the least prevalent and they are primarily composed of metal.

Over the course of Earth's 4.5 billion-year-old history, there have been several major asteroid impacts that have had a significant impact on the future of the planet and helped humanity to emerge as a dominant force. Perhaps the most consequential impact occurred almost 65 million years ago when a mammoth 12-kilometer-wide asteroid crashed into the surface and obliterated nearly 70 percent of Earth's species including dinosaurs. The crater where the asteroid crashed can still be found today in the Yucatan Peninsula in Mexico. Such large asteroids have the potential to cause global devastation if they crash. Fortunately, NASA and other space agencies now have an arsenal of space and ground-based telescopes to discover and track them.

NASA has been working on its Psyche mission for the last few years but hasn't been able to launch it yet. The space mission to the 16 Psyche asteroid has been delayed several times now, with the most recent happening on October 5. The $1.2 billion mission was set to launch via a SpaceX Falcon 9 rocket as part of NASA's Discovery missions but was delayed, giving NASA more time to reverify parameters that control the rocket's nitrogen cold gas thrusters. For the unaware, the 16 Psyche asteroid is made up of gold, nickel, and iron deposits and is supposedly worth more than Earth's economy.

Asteroids are in constant focus of most space scientists due to their potential for causing global destruction. Asteroids are space rocks that follow distinct orbits in the vastness of space. According to NASA, some of these ancient cosmic rocks pose a potential threat of colliding with Earth. Although most of them reside in the primary asteroid belt situated between the orbits of Jupiter and Mars, some of these space rocks approach Earth, with some coming within just a few hundred thousand kilometers of our planet. This proximity raises concerns about the possibility of these asteroids impacting Earth. And now, NASA has informed about a humongous asteroid that is traveling towards Earth rapidly. This is a 2200-foot asteroid that has been designated as 349507 (2008 QY).

I confess: I'm a Star Trek nerd — and commodities enthusiast, too. Thus, asteroid mining should be my personal heaven. On Sunday, I watched with the excitement of a five-year old how a NASA space probe brought back the largest-ever stash of asteroid rubble to Earth. But was this feat a step closer to commercial space mining? Not even close.

After seven years in space, NASA's Osiris-Rex probe has captured the world's attention with its successful return to Earth, carrying a precious chunk of asteroid sample. This achievement promises groundbreaking insights into the origins of our solar system and potential threats from asteroids. Notably, Osiris-Rex traveled billions of miles before jettisoning the precious cargo capsule back towards Earth. The Osiris-Rex spacecraft was some 63000 miles above Earth when it released the capsule carrying the asteroid sample, which fell back to Earth. The craft itself shot by the Earth.

NASA is on a continuous mission of exploration of the cosmos. One such mission, Psyche, scheduled to launch in October 2023, promises to unveil the secrets of a metal-rich asteroid like never before. This ambitious endeavor is set to use cutting-edge technology, including highly sensitive cameras. Asteroid Psyche follows quickly on the heels of the successful mission by NASA called DART in which the US space agency crashed a spacecraft into an asteroid in order to deflect it from its path.

NASA tracks all asteroids that stray close to the Earth because they could pose a potential danger. Apart from that, information about the origin of various asteroids can solve multiple mysteries about the universe. Recently NASA has successfully brought back a chunk of asteroid Bennu from space with the help of ORISIS- REX spacecraft. This asteroid sample is a huge achievement in the field of space exploration. Now, NASA is on its next asteroid mission called Psyche. According to NASA, this mission will study this metallic asteroid. The asteroid orbits the Sun between Mars and Jupiter. As explained by NASA, the Psyche asteroid has a nickel-iron core that was essential in creating our solar system. One of the mission's main objectives is to get as close as 280 kilometers to Asteroid Psyche. The mission will help reveal various facts about the solar system and more.

To study asteroids up close, NASA and other space agencies have launched several space missions. The purpose of these missions is to study asteroids, minimize any uncertainties around their dangers, and determine whether we could extract resources from them in the future. The Double Asteroid Redirection Test (DART) was conducted last year where a spacecraft successfully collided with an asteroid to divert it from its path. Other missions include Dawn, OSIRIS-REx, and Hayabusa2.

After yesterday's close call with Asteroid 2023 SF6, which passed Earth at a close distance of just 1.4 million kilometers, yet another asteroid approach is expected today. NASA has now revealed that an asteroid is expected to just about miss Earth. While it isn't expected to impact the surface, it could pass by very closely. NASA's Planetary Defense Coordination Office (PDCO), which is responsible for monitoring the skies against the threat of rogue asteroids, has issued a warning against the close approach of an asteroid designated as Asteroid 2023 SW6.

Asteroids are huge space rocks that revolve around in their orbits in space. According to NASA, some of these ancient space rocks present a potential threat of collision with Earth while others can help discover secrets of space. While most of them are located in the main asteroid belt between the orbits of Jupiter and Mars, these rocks often make close approaches to Earth as their orbits bring them within a couple of million kilometers of our planet. This presents a threat - could these space rocks somehow make their way to Earth? History has taught us that it certainly is possible. This can happen if an asteroid gets knocked off course, affected by a large planet's gravitational pull. Their orbits can also bring them extremely close to Earth.
