    In Pics: Spooky! NASA celebrates Halloween by sharing creepy images of Sun and more
    1/5 Have you ever seen the Sun smiling? No, we’re not cracking some lame joke. NASA recently tweeted an image where the Sun could be seen smiling! NASA tweeted, “Today, NASA’s Solar Dynamics Observatory caught the Sun "smiling." Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space.” (NASA)

    2/5 A crimson light across the sky rececntly spooked us so much that it could give Stranger Things a run for its money. NASA recently tweeted, “A flash of lightning. Then above the storm, a crimson figure blinks in & out. If you’ve ever seen one, you’re a lucky witness of a sprite!” (NASA/Thanasis Papathanasiou)

    3/5 Even astronauts dress up on Halloween! NASA recently shared an image showing four astronauts donning costumes aboard the International Space Station. NASA tweeted, “It’s time to suit up, astronauts! Are you, your friends, or kiddos wearing a space costume this Halloween? Share it with us using #NASACostume so we can see!” (NASA)

    4/5 We all knew lightning could scare us but not this way! NASA recently shared an image of thunderstorms with their tendrils across the sky. The space agency tweeted, “They flash above thunderstorms, their spiny tendrils stretching tens of miles across. A NASA scientist and night-sky fanatic chase these elusive lights across Oklahoma.” (NASA/Paul Smith)

    5/5 NASA Astronomy Image of the day – Today's image of the day is a spiral galaxy, which is the third largest in our local group of galaxies. NASA explained below the image, “The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way.” (NASA/Robert Gendler)

    Know more about this dangerous asteroid speeding towards Earth. (Pixabay)

    Did you know that almost 100 tons of dust-sized particles bombard Earth every single day. Once a year, a vehicle-sized asteroid hits Earth's atmosphere, creating a giant fireball although it burned up before reaching the surface. According to NASA, every 2000 years, an asteroid the size of a football field hits Earth and causes significant damage to the area. If you're wondering about planet-killing asteroids, they come along only once every few million years. NASA has warned that an asteroid is headed for Earth and although it might not be a planet-killer, it could still potentially cause damage if it impacts Earth.

    Asteroid 2022 UQ20 details

    NASA's Planetary Defense Coordination Office has issued an alert against an asteroid named Asteroid 2022 UQ20. The 38 feet wide asteroid is expected to fly past Earth today, November 4, at a distance of 1.1 million kilometers. The asteroid is already on its way towards Earth, travelling at a staggering speed of 29808 kilometers per hour!

    Nasa has issued a warning, classifying the Asteroid 2022 UQ20 as a “Potentially Hazardous Object” due to the close proximity with which it will pass by Earth. Although it will not collide with Earth, a slight deviation in its trajectory due to the Earth's gravitational pull can send it towards the planet for an impact.

    How is an Asteroid Orbit Calculated?

    An asteroid's orbit is computed by finding the elliptical path about the sun that best fits the available observations of the object using various space and ground-based telescopes such as NASA's NEOWISE telescope and its brand-new Sentry II algorithm. That is, the object's computed path about the sun is adjusted until the predictions of where the asteroid should have appeared in the sky at several observed times match the positions where the object was actually observed to be at those same time.
