Mars rover Perseverance saw it before we did. Read their research here.Ī SUNSPOT SO BIG YOU CAN SEE IT FROM MARS:Ī huge sunspot (AR3363) just emerged over the sun's southeastern limb. 'After carbon is exhausted in the core, a core-collapse leading to a supernova explosion is expected in a few tens of years,' write the authors. This means the giant star may be running out of carbon fuel. 28, 2023, as a show of thanks for years of service and hope for future daisies:ĬOULD BETELGEUSE EXPLODE IN OUR LIFETIMES?Īccording to a new study, the answer is 'yes.' A team of astronomers led by Hideyuki Saio (Tohoku University) find that Betelgeuse has puffed up far larger than previously thought, more than 1200 times wider than the sun. Until then, we will maintain AIM's iconic 'daily daisy,' frozen at Feb. There may be some hope of a recovery as AIM's orbit precesses into full sunlight in 2024. As a result AIM is offline, perhaps permanently. What happened to NASA's AIM spacecraft, which has been monitoring NLCs since 2007? Earlier this year, the spacecraft's battery failed. As the season progresses, these dots will multiply in number and shift in hue from blue to red as the brightness of the clouds intensifies. For the rest of the season, daily maps from NOAA 21 will be presented here:Įach dot is a detected cloud. An instrument onboard NOAA 21 ( OMPS LP) is able to detect NLCs (also known as 'polar mesospheric clouds' or PMCs). The first clouds were detected inside the Arctic Circle by the NOAA 21 satellite. The northern season for NLCs began on May 26th. There are no significant equatorial coronal holes on the Earthside of the sun. Switch to: Europe, USA, New Zealand, Antarctica

Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is intensifying, and this is reflected in the number of cosmic rays entering Earth's atmosphere. Sunspot AR3361 has developed a delta-class magnetic field that harbors energy for X-flares.
