The Parker Solar Probe (PSP; previously Solar Probe, Solar Probe Plus or Solar Probe+) [6] is a NASA space probe launched in 2018 to make observations of the Sun's outer corona. It used repeated gravity assists from Venus to develop an eccentric orbit, approaching within 9.86 solar radii (6.9 million km or 4.3 million miles) [ 7 ] [ 8 ] from ...
Asteroid (137108) 1999 AN 10 will pass within 388,960 km (0.0026 AU) of Earth. 2028 January 12 Partial lunar eclipse: 2028 January 26 Small annular solar eclipse: 2028 July 22 A total solar eclipse will be visible across Australia, including Sydney, and New Zealand. [2] Sydney will not see another total solar eclipse until June 3, 2858.
Solar maximum is the regular period of greatest solar activity during the Sun's 11-year solar cycle. During solar maximum, large numbers of sunspots appear, and the solar irradiance output grows by about 0.07%. [2] On average, the solar cycle takes about 11 years to go from one solar maximum to the next, with duration observed varying from 9 to ...
In 2024, the sun enters its solar maximum—birds don't know what's about to hit them. Space weather may seriously send their internal compasses into disarray. In 2024, the sun enters its solar ...
Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. [2] It is expected to continue until about 2030. [3] [4]
[1] [2] It began in December 2008 with a minimum smoothed sunspot number of 2.2, [3] [failed verification] and ended in December 2019. [4] Activity was minimal until early 2010. [5] [6] It reached its maximum in April 2014 with a 23 months smoothed sunspot number of 81.8. [7]
The solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25.
The Helios project set a maximum speed record for spacecraft of 252,792 km/h (157,078 mph; 70,220 m/s). [3] Helios-B performed the closest flyby of the Sun of any spacecraft until that time. The probes are no longer functional, but as of 2024 remain in elliptical orbits around the Sun.
