What are solar radiation storms and their impact on Earth?

[ad_1] Every now and then we hear about solar storms and solar flares being spewed out by the Sun and the impact it has on Earth including on satellites and power grids. But have you heard about solar radiation storms? Before discussing the term, let's first know what are solar storms and solar flares.NASA describes a solar flare as an intense blast of radiation caused by the release of magnetic energy from sunspots. Whereas, solar storms refer to the atmospheric consequences on Earth due to space events like coronal mass ejections and solar flares originating from the Sun. What is a solar radiation storm?According to the Space Weather Prediction Center reported, solar radiation storms are large-scale magnetic eruptions that cause coronal mass ejections (CME) and associated solar flare....

Saving Earth from asteroids to microbes: Planetary Protection Vs Planetary Defense

[ad_1] We all have been hearing about the terms planetary protection and planetary defense being used by the official in a different yet similar manner. But do you actually know what they mean and how researchers and astronomers used these terms?Both of the terms include “planetary” so their meanings and behaviours must be comparable. However, this is the only resemblance between them; their distinct responsibilities are what set them apart. They have very different outlooks in terms of the agency's role in protecting Earth, and other planets as well. “These similar sounding efforts are often confused in the media and in casual conversation,” said Nick Benardini, NASA Planetary Protection Officer. “Both seek to protect Earth from potentially hazardous space threats, but otherwise they c...

The solar storm that shook the solar system, know all about the shocking Bastille Day event

[ad_1] On July 15, 2000, the Earth was hit by an unexpected solar storm. The storm was sparked by a coronal mass ejection (CME) that was released after an X5.7-class solar flare erupted on the Sun. The terrifying event was witnessed by the NASA Solar and Heliospheric Observatory, which was launched just five years earlier. But that was not the only NASA spacecraft to witness the solar storm. The Voyager 1 spacecraft, which was placed at the edge of the solar system, also felt the shockwaves produced by the flare eruption. Today, this event is known as the Bastille Day solar storm, and as it completes its 23rd anniversary, let us know more about it.According to a report by SpaceWeather.com, “Its impact on July 15, 2000, sparked an extreme (Kp=9) geomagnetic storm. By the time the storm s...

NASA telescopes track 65-foot asteroid approaching Earth at breakneck speed

[ad_1] Asteroids are described as ancient space rocks left over from the early formation of our solar system around 4.6 billion years ago. These objects pass Earth occasionally at safe distances. NASA has carried out several missions to these rocks to study them up close. While the DART Test was in the news last year as the first-ever planetary defense test, the space agency also carried out missions like Dawn, OSIRIS-REx, and Hayabusa2.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. Research on asteroids is critical since it can provide valuable information on the early stages of the solar system and planetary development. Furthermore, these celestial bodies mi...

Largest ‘mirror’ in the Universe! Check out this unique exoplanet

[ad_1] Europe's Cheops Space Telescope has discovered a scorching hot exoplanet where metal clouds and rain drops of titanium are making it the most reflective planet ever seen outside our solar system. The planet is located 260 light years away from Earth which reflects 80 percent of the light from its host star.Astronomers believe that the exoplanet can match Venus' shininess and planet LTT9779 b which was found earlier in 2020 and orbits its star in just 19 hours. About the newly discovered exoplanetAccording to ESA. the exoplanet is the same in size as Neptune, making it the largest “mirror” in the Universe. Its exceptional reflectivity can be attributed to the presence of metallic clouds. These clouds consist mainly of silicate. The researchers believe the planet's size and tempera...

Physicist who found spherical meteor fragments claims they may come from an alien spaceship

[ad_1] Avi Loeb, a physicist from Harvard University in the US, has recovered 50 tiny spherical iron fragments from the bottom of the Pacific Ocean that he claims may be material from an interstellar alien spaceship.Loeb is linking his finding with the passage of a fireball in January 2014. The meteor was observed by sensors of the US Department of Defense that track all objects entering the Earth's atmosphere. It was recorded as travelling faster than most meteors and eventually broke up over the South Pacific Ocean near Papua New Guinea. at a on the object is held by Nasa's Centre for Near Earth Object Studies (CNEOS). The meteor's official name is CNEOS 20140108, and is also referred to as IM1 (for interstellar meteor). There is a very large scientific leap from observing a fireball ...

Earth will get under 20 min solar storm warning before it hits power grid

[ad_1] The world may have as little as 20 minutes to prepare for a solar storm that could severely impact power grids, it has been revealed. With solar activity expected to reach its peak in 2025, Earth's energy grids may not be adequately equipped to handle the consequences, The National News reported.The powerful bursts of energy emitted by the Sun during solar storms have the potential to cause physical damage and trigger magnetic storms that disrupt systems on the ground. Unfortunately, long-range forecasting in this field is currently inadequate, according to an official from the UK's Met Office, which is responsible for predicting space weather. While short-term forecasts are relatively accurate, predicting events over a longer timeframe proves challenging. Solar storms can also h...

NASA’s James Webb Space Telescope unveils breathtaking view of Saturn

[ad_1]  The image released by NASA showcases intricate details within Saturn's mesmerising ring system, even offering glimpses of some of its moons, such as Dione, Enceladus, and Tethys. The research team plans to conduct deeper exposures, hoping to explore the planet's fainter rings, including the elusive G ring and the diffuse E ring, which remain hidden in this particular image. Saturn's rings, composed of a diverse array of rocky and icy fragments ranging in size from minuscule grains of sand to colossal mountains, have long been a source of fascination for scientists and stargazers alike. This new image from Webb provides a unique perspective on their composition and structure, shedding new light on their mysterious nature. Apart from the rings, Saturn's atmosphere also reveals ast...

World Asteroid Day 2023: History, Significance, and Ways to Celebrate

[ad_1] World Asteroid Day is an annual event that takes place on June 30th to raise awareness about asteroids and their potential risks to our planet. This significant date was chosen to commemorate the Tunguska event, an enormous explosion caused by a asteroid in Siberia in 1908.History of World Asteroid DayThe establishment of World Asteroid Day dates back to 2014 when Brian May, known for his role in the rock group Queen, joined forces with Apollo 9 astronaut Rusty Schweickart, filmmaker Grig Richters, and B612 Foundation president Danica Remy. The specific date of June 30th was selected to honour the Tunguska event, which occurred on June 30, 1908. During this incident, a large asteroid exploded in the atmosphere over Siberia, Russia, resulting in the flattening of approximately 2,1...

Shocking encounter! NASA says asteroid dashing towards Earth at 9933 kmph

[ad_1] 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.Even though there are millions of asteroids in our solar system, only a handful of them have been observed, with the current asteroid count being roughly 1,298,148. One of these asteroids is heading towards Earth for close approach soon, NASA has revealed. Asteroid 2023 LG2The asteroid that will c...
