1/5 Asteroid 2023 QG: NASA's JPL has spotted an asteroid named 2023 QG, which is heading toward Earth on September 2. This asteroid is about 240 feet in size and it will approach Earth at a speed of 49,322 Km per hour. Don't worry, though, because it will pass at a distance of 4.43 million kilometers from our planet. This asteroid is about the size of an airplane. (Pixabay)

2/5 Asteroid 2017 QH1: Another asteroid, 2017 QH1, is also coming close to Earth today on September 2. Its size is around 73 feet and It passed Earth at a speed of 22,872 kilometers per hour and pass by Earth at a distance of 5.01 million kilometers. This asteroid poses no threat to us due to its small size. (Pexels)

A spectacular northern lights show lit up the sky early on Sunday morning, delighting people and filling social media with stunning pictures. This amazing display was caused by a solar storm that was expected to pass by Earth on Saturday. The experts at NOAA's Space Weather Prediction Center had originally predicted a minor geomagnetic storm (G1) for Saturday night into Sunday morning. However, it turned out to be a much stronger G2 event, making the Northern Lights visible even in areas closer to the equator.

The timing and strength of the geomagnetic storm were a bit uncertain because it depended on when the coronal mass ejection (CME) from the Sun reached Earth and how much it affected our planet's magnetic field.

During a G1 or G2 storm, one of the most common effects is that the Northern lights appear further south than usual. These beautiful displays are caused by solar flares from the Sun. The charged particles from these flares interact with the gases high up in our atmosphere, creating different colours of light. NASA explains that the colours vary because of different gas particles in the atmosphere and the type of light they emit.

People across North America, from Alaska to New Hampshire, and even in places like Newfoundland, Quebec, Ontario, British Columbia, and the Prairies, captured these breathtaking auroras and shared them on social media platforms like X (formerly Twitter).

What are Coronal Mass Ejections (CMEs)?

Coronal Mass Ejections, or CMEs, are massive bursts of plasma and magnetic fields from the Sun's outer layer, called the corona. They can release billions of tons of material and carry a strong magnetic field. CMEs travel at different speeds, with some reaching Earth in as little as 15-18 hours, while others take several days. As they move away from the Sun, CMEs grow in size, and some can cover a significant portion of the space between Earth and the Sun when they arrive.
