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 Astronomy Picture of the Day 16 June 2023: Aurora – From sunset to sunrise

[ad_1] It's NASA Astronomy Picture of the Day (APOD) birthday! It was first launched on June 16, 1995 by Robert Nemiroff and Jerry Bonnell. With a vast collection of astronomical images, the APOD archive stands as the largest repository of its kind on the internet, NASA says. Each day NASA features a different picture of some part of our fascinating universe, along with a brief explanation written by a professional astronomer.Today's NASA astronomy photo of the day features a timelapse from sunset to sunrise with an aurora. A breathtaking view from the coast of Sweden's coastline gazes over the Baltic Sea, capturing the essence of time within a single photograph. Within this image, an entire night unfolds! From sunset to sunrise, the moon's radiance illuminates the sea and skyscape alon...

NASA Astronomy Picture of the Day 11 June 2023: What is the TRUE colour of the Sun?

[ad_1] What Color is the Sun? The answer to this question seems obvious -- yellow. That's what we see on a daily basis, right? But you would be surprised to know, that the true colour of the Sun is not absolute Yellow or even White. Seems confusing? Don't worry, NASA has covered it all! According to the space agency, the colour that we perceive is undeniably influenced by various factors. These include the wavelength and intensity of the light being emitted, environmental conditions, the capabilities and restrictions of our eyes in capturing light, and ultimately, the functioning of our brains.Today's Astronomy Picture of the Day is actually the colour spectrum of the Sun. However, there are some missing colours too! The spectrum shared by NASA has the complete range of observable colou...

NASA Astronomy Picture of the Day 17 May 2023: Dark Sunspots

[ad_1] Yesterday we saw NASA Astronomy Picture of the Day feature an image of the Sun's Corona which was captured during a total solar eclipse. It was a particularly special image as the Corona can only be seen during the solar eclipse when the Sun's when the main radiation from the Sun's surface is blocked by the Moon. NASA publishes the Astronomy Picture of the Day everyday, featuring pictures captured by astrophotographers around the world. Today's picture is another special image of the Sun.Today's NASA Astronomy Picture of the Day is a snapshot of Sunspots on the surface of the Sun in the active region AR 3297. According to NASA, Sunspots are dark areas on the solar surface which contain strong magnetic fields that are constantly shifting and can form and dissipate over periods of ...

NASA Astronomy Picture of the Day 16 May 2023: Sun’s Corona visible during solar eclipse

[ad_1] NASA publishes its Astronomy Picture of Day on a daily basis, featuring stunning photographs of celestial bodies captured by astrophotographers from around the world, and they always leave us mesmerized. At the center of our solar system is the Sun, a hot glowing ball of hydrogen and helium. It is about 150 million kilometers away from Earth and is the largest object in our solar system, big enough to fit nearly 1.3 million Earths in it. According to NASA, the Sun is about 4.5 billion years old and it is one of the main reasons why everything in our solar system stays in its orbit.Today's NASA Astronomy Picture of the Day is a snapshot of the Sun's Corona visible during a total solar eclipse. Temperatures in the Sun's Corona can reach up to 2 million degrees and it is also the re...

Solar storm delayed! But there is WORSE news coming for Earth

[ad_1] Amazingly, astronomers are perplexed right now. A solar storm was predicted to strike the Earth on either April 27 or 28 by the National Oceanic and Atmospheric Administration (NOAA). The storm was going to be triggered by a glancing blow from a coronal mass ejection (CME) which was headed for the Earth. But for some reason, it has not arrived yet. While this could mean that the CME missed the Earth entirely, some believe this is too early to celebrate and could mean a bigger worry for our planet. The delayed solar storm can, in theory, cause worse damage to infrastructure on Earth.According to a SpaceWeather report, “A CME expected to hit Earth on April 27th has not yet arrived. It might have missed”. While NOAA believes there is a small chance that it can still strike today, Ap...

Massive EXPLOSION on Sun blasts CME; Solar storm to wreak havoc on Earth

[ad_1] A few days ago, several astronomers warned about the high number of magnetic filaments present on the Earth-facing side of the Sun. These looping structures are filled with plasma and magnetic fields and they are set off randomly causing big explosions on the surface of the Sun. And just hours ago, today, April 21, the NASA Solar Dynamics Observatory spotted a massive blast in one of the filaments. It was also seen that a massive coronal mass ejection (CME) cloud was also hurled toward our planet. Early predictions indicate that the resultant solar storm can be a dangerous one.The information comes from a SpaceWeather report which noted on its website, “A magnetic filament snaking across the sun's southern hemisphere erupted today, hurling a CME toward Earth. The explosion defini...

Solar winds moving at a hellish 600 km per second, COLLIDE with Earth as solar storm terror continues

[ad_1] Solar activity has been on the rise ever since the turn of 2023, but the month of March in particular witnessed some record-breaking solar storms. In the second week of the month, the Earth suffered the blow of a G3-class geomagnetic storm that delayed a SpaceX rocket launch and disrupted the operations of oil rigs in Canada. Worse was to come. In the third week of March, the worst solar storm in six years, a G4-class geomagnetic storm struck the Earth. And now, the planet must brace for another ordeal as solar winds, moving as fast as 600 kilometers per second, have struck the Earth. Forecasters have also issued a solar storm warning for later today.The incident was reported by SpaceWeather.com which noted in its website, “Earth is entering a stream of solar wind flowing 600 km/...

Surreal! NASA shares DEAFENING screams of the Sun; Listen to the scary sound

[ad_1] Last month, NASA made a remarkable discovery when it recorded the sound coming from RS Puppis, a Cepheid variable star which is located about 6,500 light-years away. But that's not all the sound we can hear from space. Our own star, The Sun, also makes a really eerie sound that is so loud it could even deafen everyone on Earth. This would happen if sound could propagate through space. But because it doesn't, we have never heard it before. But the NASA Solar and Helioscopic Observatory, a spacecraft tasked with monitoring the Sun, has captured the sound coming from it using an instrument known as Michelson Doppler Imager (MDI).Posting the raw audio on YouTube, the official YouTube channel of NASA said, “These are solar sounds generated from 40 days of the Solar and Heliospheric Ob...

Solar storm DANGER! NASA spots giant hole on Sun blasting solar winds towards Earth

[ad_1] Yesterday, March 20, it was reported that the Earth may suffer a glancing blow from an incoming coronal mass ejection (CME) today. While astronomers keep an eye out on its development, a far more concerning development has been spotted on the Sun. The NASA Solar Dynamics Observatory has detected a large hole in the Sun's atmosphere which is spewing a stream of solar winds. This solar wind is expected to reach our planet between March 23 and 24, and can cause another powerful solar storm event. Things can worsen if there is any incoming CME on that day as the resultant effect would be multiplied due to the effect of solar winds. Check details.The development was reported by SpaceWeather.com which noted on its website, “A large hole has opened in the sun's atmosphere, and it is sp...
