The Sun’s solar cycle began on 25 2019, and is expected to reach its apogee in July 2025. This is the main reason for the recent eruption of the Sun. Flares, prominences, sunspots, coronal mass ejections are common triggers of solar activity, as are plates and other related phenomena seen at other wavelengths. Unfortunately, Earth is going through a rough patch. A G5 class solar storm, which is terrifyingly powerful, could damage satellites by hitting Earth, disrupting wireless communications such as the Internet, mobile phone networks and GPS, as well as disrupting the power grid. Scarily, it can also interfere with electronics like pacemakers.
NASA’s Astronomy Photo of the Day is a snapshot of the increasing activity on the Sun’s surface. The image was taken two weeks ago in a color of light known as hydrogen alpha, and several interesting features on the solar surface can be imaged. Solar energy can be seen ejected from the surface while the edges of the Sun are illuminated by the absorption of relatively cool solar gas.
This photo was taken by astrophotographer Mehmet Ergun.
NASA image description
our the sun Becoming a busy place. Just two years ago, the sun At least the solar was rising so quietly that weeks would pass without a single sunspot. In contrast, already this year and well ahead of schedule, our Sun is unusually active, already nearing the level of solar activity seen during the last solar maximum a decade ago. Our fast-moving Sun was captured two weeks ago with a number of interesting features.
The image was recorded in a single color of light called hydrogen alpha, color inverted, and false color. Speckles carpet most of the Sun’s face. Flares towards the edges of the Sun are caused by the absorption of relatively cool solar gas and are called limbic darkening. Just outside the Sun’s disk, several glowing prominences emerge, while the prominences on the Sun’s face are known as filaments and appear as faint streaks. Magnetically entangled active regions are both dark and light and contain the coldest areas of the Sun. As our Sun’s magnetic field moves toward the solar maximum over the next few years, it is not known whether the Sun’s high activity will continue to increase.
