Best NASA Astronomy Pictures of the Week: Geomagnetic storms, Tarantula Nebula and more
Medulla Nebula Supernova Remnant
1/5 The Medulla Nebula Supernova Remnant (April 24) - It is CTB-1, also known as the Medulla Nebula Supernova Remnant. It is a rare cosmic bubble and the remnant of an ancient supernova explosion that occurred about 10000 years ago, according to NASA. The Medulla Nebula Supernova Remnant is given the name because of its brain-like shape and is located towards the constellation of Cassiopeia. (NASA/Kimberly Sibbald)
2/5 Geomagnetic Storm sparks Auroras (April 25) - Stunning auroras sparked by the G4-class geomagnetic storm were captured from Caceres, Spain. But it wasn’t just Spain where the auroras were visible. According to a report by, the stunning streaks of light were seen lighting up the sky in Europe, in several parts of the U.S., New Zealand and as far as south of France.  (NASA/Landon Moeller)
Full Moon
3/5 Full Moon shot through Arc de Triomphe (April 26) - This captured image is a fascinating snapshot of the full Moon through the Arc de Triomphe in Paris, France. The amount of Moon we see changes over the month, which is known as the lunar phases, and there are 8 in total - New Moon, waxing crescent, first quarter, waxing gibbous, full Moon, waning gibbous, third quarter and waning crescent Moon.

Tarantula Nebula
4/5 The fascinating Tarantula Nebula (April 27) - is the 30 Doradus, also known as the Tarantula Nebula, located about 160,000 light-years away towards the constellation of Dorado. The 30 Doradus is also called the Tarantula Nebula because of its glowing filaments which resemble spider legs, according to NASA. The Nebula is special as it can be seen in the Southern sky with the naked eye. It resembles a large milky patch of stars when viewed from Earth. (NASA/SuperBIT)
runaway star Alpha Camelopardalis
5/5 Runaway star Alpha Camelopardalis (April 28) - It is a snapshot of Alpha Camelopardalis, a runaway star located about 4,000 light-years away in the long-necked constellation Camelopardalis. According to NASA, this star is moving through space at a rapid speed of about 60 kilometers per second. In fact, this star is about 25-30 times the size of our Sun and over 500,000 times brighter! NASA has also revealed that Alpha Camelopardalis is 5 times hotter than our Sun, with a temperature of about 30,000 Kelvin. (NASA/Andre Vilhena)

The first solar eclipse of 2023 which took place on April 20, 2023 gave a unique opportunity to people to watch a hybrid solar eclipse. But now the images captured by Astronomers Petr Horalek of the Institute of Physics in Opava, and Josef Kujal, Milan Hlavac of the event have left people amazed both. The images show unearthly or ghostly eruptions coming out from the Sun.

The unique celestial event of April 20, has given a peek at the eruption and corona of the Sun to the astronomers. Sharing the image Petr Horalek stated on his website, "On April 20, 2023 a unique hybrid solar eclipse occurred over the Indian Ocean, Australia, and Indonesia, making the opportunity to see a ghostly corona for up to 1 minute in the central line above Exmouth of Australia."

"I was lucky to get there for the spectacular phenomenon. Here are some first results of the phenomenon and also the atmosphere around it. Excitements were huge over the Pebble Beach, where over 300 people parked their cars to see the 1-minute totality with huge prominence and solar-max-shaped corona," he added.

The image shows the moment of the diamond ring phenomenon when the eclipse ends. Peter further informed via his website that "You can notice CME events in the solar corona as well in the image. Some reflections made the result worse considering there was only 1 minute to take the image sequence, but the final view reveals more than was visible to the naked eye.

It can be known that a Coronal Mass Ejection (CME) are huge bubbles of coronal plasma threaded by intense magnetic field lines that are ejected from the Sun over the course of several hours. They often occur along with solar flares (explosions on the Sun's surface), but they can also occur spontaneously. The frequency of CMEs varies with the 11 year solar cycle.

According to NASA, CMEs disrupt the flow of the solar wind and cause disturbances that can damage systems in near-Earth and on Earth's surface. Their magnetic fields merge between the interplanetary magnetic field (IMF) and geomagnetic field lines. This direct link between even a small percentage of the geomagnetic field lines and the IMF results in large increases in the rate of energy transfer from the solar wind and the magnetosphere. Because of this, CMEs are among the most important drivers of geomagnetic storms and substorms.

Hybrid solar eclipse

A solar eclipse occurs when the Sun, the Moon, and Earth line up, either fully or partially. Depending on how they align, eclipses provide a unique, exciting view of either the Sun or the Moon. "A solar eclipse happens when the Moon passes between the Sun and Earth, casting a shadow on Earth that either fully or partially blocks the Sun's light in some areas," NASA said. While a hybrid solar eclipse takes place when a total eclipse and the annular solar eclipse occur at the same time.
