• X1.9 solar flare took place

    Sunspot 1302 is back at it again, this time producing an X1.9 Solar Flare at 09:40 UTC. This major event resulted in an R3 level radio blackout as well as producing a 10.7cm Radio Burst (TenFlare). A fast moving type II sweep frequency event is reported also. As this

  • Where is UARS?

    NASA says it continues to wait for final confirmation of re-entry. "If debris fell on land (and that's still a BIG if), Canada is most likely area," the space agency just said on their twiter.  It is still unconfirmed but it looks like the place of

  • UARS reentry update! Where will it fall?

    NASA’s UARS satellite is making its last orbits around Earth. Orbital elements just published by US Strategic Command suggest that re-entry could occur a little later than previously expected.”For now, it looks like 00:00 – 04:00 UTC on Sept. 24,” says satellite

  • Seeing equinoxes and solstices from space

    One of the most frequently misunderstood concepts in science is the reason for Earth’s seasons. As we experience the September equinox today—anyone try to balance an egg yet?—we thought we’d offer a space-based view of what’s going on.Around 6 a.m. local

  • Long duration X1.4 solar flare took place at new sunspot

    Earth-orbiting satellites have detected a long-duration X1.4-class solar fare coming from a new sunspot on the sun’s eastern limb. The blast, which peaked at 1100 UT, produced a significant CME, but the cloud is not Earth-directed.

  • UARS re-entry update

    NASA has issued an update on the condition of the decaying UARS satellite: “As of 1:30 p.m. EDT Sept. 21, 2011, the orbit of UARS was 120 mi by 130 mi (190 km by 205 km). Re-entry is expected sometime during the afternoon of Sept. 23, Eastern Daylight Time. The

  • Earth-directed coronal mass ejection expected

    A coronal mass ejection (CME) is heading toward Earth and it could deliver a glancing blow to our planet’s magnetic field on Sept. 22th around 23:00 UT. There are no large coronal holes on the Earth-facing side of the sun. High-latitude sky watchers should be alert for

  • How can we see the Sun and the Moon at the same time?

    Many people only notice our Moon at night, when there is considerably more contrast between the Moon and the night sky. Being the second brightest object in the sky (after the Sun, of course) and with Venus visible during the day to trained eyes, it’s no real

  • The mission to find the missing lunar module

    Where is the Apollo 10 Lunar lander module? It’s somewhere out there — orbiting the Sun — and there’s a new initiative to try and find it!The Apollo 10 mission launched on May 18, 1968 and was a manned “dry run” for its successor Apollo 11, testing all of
