Time-Lapse Image Captures Stunning Sunspots As Sun Becomes More Active

Our solar system’s central star, or the Sun as we know it is a fascinating piece of an everlasting cosmic puzzle. With tremendous achievements made in the realm of remote space exploration over the last decade, we now have visual access to our solar system unlike ever before.

A beautiful new time-lapse photo shows shape-shifting sunspots moving across the Sun’s surface. An image is never just an image in space – scientists noted that the total number of sunspots on our host star was at its highest in eight years. This means that solar activity could increase further.

Sun’s entering active phase

The new time-lapse photo was created by Şenol Şanlı, an amateur astrophotographer from Turkey. For this purpose, Şanlı used data from NASA’s Solar Dynamics Observatory. The image was shared on his Instagram on January 3 and is a composite of two individual images taken between December 2 and December 27, 2022.

The two different bands of sunspots that can be seen in the image belong to two sunspot groups – A3176, located in the Sun’s northern hemisphere; and A3153, in the Sun’s southern hemisphere, as reported by Space.com. Both of these sunspot groups moved from east to west (right to left in the image).

By removing other visible sunspots from the images, Şanlı brought to attention the smallest changes in the sunspot groups.

While these spots might look small and benign from Earth, they’re actually bigger than most planets in our solar system. Sunspots are also not black, but appear dark owing to their cooler temperatures compared to rest of the star.

Sunspots are of immense interest to scientists for solar flares and coronal mass ejections (CMEs) emanate from such spots. In December 2022, more than 113 sunspots were detected on the Sun’s surface – the highest number since 2014 according to Space Weather Prediction Center.

The Sun is currently entering the active phase of its 11-year solar cycle, which scientists think should peak in 2025. What do you think about these beautiful sunspots? Let us know in the comments below.

A hyperactive sunspot to result in solar flares

Images taken of the sun on December 4 by Eduardo Schaberger Poupeau, an astrophotographer, revealed five significant sunspots and two filaments of magnetism facing Earth. “In the southeast limb, we see an extensive prominence, also in the southern hemisphere, but within the disk, we can see the active region AR3153 that contains sunspots of a significant size, we also see a very extensive filament,” Poupeau told Spaceweather.com. 

According to Nasa, a solar flare is described as an “intense burst of radiation coming from the release of magnetic energy associated with sunspots.” It is considered to be the largest explosive event in our solar system. “They are seen as bright areas in the sun and they can last from minutes to hours.”

Do all solar flares reach Earth? 

The activity on the solar surface impacts earth only when it takes place on the side of the sun facing Earth. Since the flares are made of photons, their visibility can lead to direct impact. 

The cause of such flares can be attributed to sunspots, “which are dark areas on the solar surface, contain strong magnetic fields that are constantly shifting”. When these fields quickly dissipate their stored energy, it can lead to the formation of solar flares and coronal mass ejections (CMEs). For reference, a “moderate-sized sunspot is about as large as the Earth”.
