Best NASA Astronomy Pictures of the Week: Volcano on Mars, first 3D-printed rocket, more
Olympus Mons volcano
1/5 Olympus Mons on Mars (April 3) – NASA shared Olympus Mons, the largest volcano in the solar system which is located on Mars. How tall is it? NASA says that it has an elevation of about 25kms above the surrounding plains, stretching almost 600kms across. This image was captured by the Mars Express mission.  ( ESA/ DLR/ FU Berlin/Mars Express/Andrea Luck)
Rubin's Galaxy
2/5 Rubin's Galaxy (April 5) – Captured by the Hubble Telescope, NASA featured Rubin's Galaxy (UGC 2885), which is located around 232 million light-years away in the northern constellation Perseus. Also, it spans around 800000 light-years across. (NASA/ESA/Hubble Telescope/B. Holwerda)
Terran 1
3/5 World's first 3D-printed rocket (April 6) – It is Terran 1. Built by Relativity Space, Terran 1 can carry payloads up to 1250kg to about 185kms of Low-Earth orbit. (NASA/John Kraus/Relativity Space)
Supergiant star Rigel
4/5 Rigel - the brightest star of Constellation Orion (April 7) – Rigel is a blue-white shining star and is among the top 10 brightest stars visible from Earth. This supergiant star is believed to be approximately 8 million years old and is significantly larger and more massive than the Sun.  (NASA/Rheinhold Wittich)
Spiral Galaxy
5/5 Giant 100-bn star Spiral Galaxy (April 8) – It is Messier 100 (M100), a grand spiral galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy. It is 56 million light-years distant towards the constellation of Berenice's Hair (Coma Berenices). ( NASA, ESA, Hubble)

Recently, a minor shortwave radio blackout over the Indian Ocean area due to a newly formed sunspot which exploded, spitting out an M3-class solar flare on April 6. The affected countries included India, Sri Lanka, Bangladesh and even China, Japan, and South Korea. The Sun has gradually become violent due to its Solar Cycle 29 which is expected to hit its peak in July 2025. Therefore, Earth is in for a rough ride until then. Recently, the Sun spewed out C-class solar flare which could make its way towards Earth soon.

According to a report by the U.S. National Oceanic and Atmospheric Administration (NOAA), as many as 19 C-class flares were produced by the Sun yesterday, April 9. The strongest of them was a C-9.1 solar flare, just shy of an M-class solar flare which was hurled out. What's shocking in 18 of these solar flares originated from a single region known as AR3272 which has an unstable beta-gamma field, according to

There is a 95% chance of C-class solar flares hitting Earth today, but that is not it. As per the report, there is a 30% chance for M flares, and a 5% chance for X flares too.

Effects of solar activity

While Earth's magnetosphere deflects most solar activity carried by the solar wind, some charged particles seep through. These energetic particles cause magnetic disturbances, classified as either geomagnetic storms or substorms. These storms can cause stunning sky phenomena known as Auroras or Northern Lights.

When solar particles hit Earth, the radio communications and the power grid is affected when it hits the planet's magnetic field. It can cause power and radio blackouts for several hours or even days. However, electricity grid problems occur only if the solar flare is extremely large.

How NASA monitors solar activity

Among many satellites and telescopes observing the Sun currently, one is the NASA Solar Dynamics Observatory (SDO). The SDO carries a full suite of instruments to observe the Sun and has been doing so since 2010. It uses three very crucial instruments to collect data from various solar activities.

They include Helioseismic and Magnetic Imager (HMI) which takes high-resolution measurements of the longitudinal and vector magnetic field over the entire visible solar disk, Extreme Ultraviolet Variability Experiment (EVE) which measures the Sun's extreme ultraviolet irradiance and Atmospheric Imaging Assembly (AIA) which provides continuous full-disk observations of the solar chromosphere and corona in seven extreme ultraviolet (EUV) channels.
