📸 An Almost Everything Sky
This surprising sky has almost everything. First, slanting down from the upper left and far in the distance is the central band of our Milky Way Galaxy. More modestly, slanting down from the upper right and high in Earth's atmosphere is a bright meteor. The dim band of light across the central diagonal is zodiacal light: sunlight reflected from dust in the inner Solar System. The green glow on the far right is aurora high in Earth's atmosphere. The bright zigzagging bright line near the bottom is just a light that was held by the scene-planning astrophotographer. This "almost everything" sky was captured over rocks on Castle Hill, New Zealand late last month. The featured finished frame is a combination of 10 exposures all taken with the s...

☄️ Lifting the canopy on Earth’s forests
ESA’s state-of-the-art Biomass mission has been designed to shed new light on the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the radar signal can slice through the forest canopy and whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.

🌌 Hubble celebrates 35th year in orbit
In celebration of the NASA/ESA Hubble Space Telescope’s 35 years in Earth orbit, an assortment of images that were recently taken by Hubble has been released today. This stretches from the planet Mars to images of stellar birth and death, and a magnificent neighbouring galaxy. After over three decades of scrutinising our Universe, Hubble remains a household word as the most well-recognised telescope in scientific history.
