[ad_1] The Sun's Solar cycle 25 commenced in 2019, and it is anticipated to reach its zenith in July 2025. This is the primary cause of the Sun's recent outbursts. Flares, prominences, sunspots, coronal mass ejections are the common harbingers of solar activity, as are plages and other related phenomena seen at other wavelengths. Unfortunately, the Earth is in for a challenging period. A G5-class solar storm, which is the horrendously powerful, striking the Earth can lead to the damage to satellites, interference in wireless communications like internet, mobile phone network and GPS, as well as power grid failures. Terrifyingly, it can even disrupt electronics such as pacemakers.NASA's Astronomy Picture of the Day is a snapshot of the rising activity on the surface of the Sun. This ima...

[ad_1] NASA Astronomy Picture of the Day 20 February 2023: Our universe is illuminated by trillions of stars in the sky. These bright objects are formed in a giant cloud of dust and gas in space, known as a Nebula. After formation, many stars form groups from the same Nebula, forming a Star Cluster. Star clusters can contain as few as ten stars or as many as millions of stars. Sometimes, sky watchers might confuse star clusters in our own Milky Way Galaxy with clusters in other galaxies due to their similar appearance.One of these star clusters is NGC 1850, which makes NASA's Astronomy Picture of the Day. It is a 100-million-year-old globular star cluster located 160,000 light-years away in the constellation Dorado. What's unusual about this star cluster is its size and shape is remini...
