Winter Skywatching

It may be cold outside, but there are still some sights in the night sky this winter that shouldn't be missed, including some amazing line-ups of planets and the Moon, and the elusive Zodiacal Light!

Watch for these amazing planetary conjunctions! Here's when

This Year in Space

There are some awesome events happening in astronomy and space exploration in 2018. Here's a list of the best things going on in space this year.

Super Blue Blood Moon and Falcon Heavy launch kick off amazing year in space!

The Sun and Space Weather

NASA's Solar Dynamics Observatory (SDO) monitors the Earth-facing side of the Sun, 24 hours a day, 365 days a year, tracking sunspots, solar flares, filament eruptions and coronal mass ejections, to provide us with ample warning should solar activity potentially threaten our satellites, spacecraft and astronauts in orbit, and our power grids on the ground.

Above are five different views that SDO regularly delivers - Track sunspots with the HMI Intensitygram (Orange), see dark filaments and prominences with the 304 Angstrom filter (Red), marvel at magnetic 'coronal loops' with the 171 Angstrom filter (Gold), spot solar flares the 94 Angstrom filter (Green), and see the solar corona (the Sun's "atmosphere") with the 193 Angstrom filter (Bronze).

Solar activity can have direct impact on Earth, our people and technology in space, and our power grids and technologies here on the ground, in the form of Space Weather.

You can track space weather from the products below.

See the overall activity around Earth with NOAA's Space Weather Overview, on the left above, including the Planetary K-index, which measures geomagnetic activity (Kp=5 or higher is a geomagnetic storm!). Track Coronal Mass Ejections and the solar wind using the WSA-Enlil Solar Wind Prediction model, on the right above. In the model, Earth is the green dot in both plots, CMEs show up in the top plot as bright arcs of colour, expanding as they move outward from the centre, and the solar wind looks like a brightly coloured 'pinwheel' in the bottom plot.

Check out how far south the auroras may reach in the next 30 minutes with the Aurora Forecast for the northern hemisphere (left). Watch the streams of solar particles that leave the Sun, to form the bright pinwheel of the solar wind, and track CMEs expanding outward following solar flares, using the latest LASCO C2 closeup view of the solar corona (centre) and the latest LASCO C3 wide-field view of the corona (right).

All of these images update on a regular basis. Simply refresh the page to load the latest, or click on an image to see more info (opens a new tab).

Global Carbon Dioxide

The Keeling Curve, provided by the Scripps Institution of Oceanography, gives the daily reading of atmospheric carbon dioxide, measured at the top of Mauna Loa, Hawaii.
