I think this #dotastro video from @astropixie is worth watching again :)
Timelapse of clouds at Observatorio del Teide, Tenerife
Saturn and the Moon, seen last night through the 50cm Mons telescope. Sorry for image quality: held my iPhone up to the eyepiece!
I appear to be standing on Mars (in Tenerife). Can’t find Curiosity anywhere…
Parts of Tenerife look a lot like sets from Star Trek. It’s a good thing.
Check out this amazing new Hubble image of the Horsehead Nebula. This image has been released to celebrate Hubble’s 23rd year in orbit. It’s taken in the near-infrared and shows mind-blowing details and complexity in the structure of this famous astronomical object.
The Horsehead is located in Orion and is a favourite for astrophotographers around the world. Normally seen as a dark patch on a bright, diffuse cloud - this IR image shows the glowing dust that makes up the nebula and the detailed structures that ebb and flow within it.
This diagram compares the planets of the inner solar system to Kepler-62, a five-planet system announced today, which is about 1,200 light-years from Earth. Two planets in this system are not much bigger than Earth and orbit their star in the Goldilocks Zone, where it’s not too hot and not too cold for liquid water: but just right.
The Madagascar Periwinkle is now found in tropical regions around the world as an ornamental plant.
It contains more than 70 highly-toxic alkaloids to deter animals from eating it. In the 1950s two of these alkaloids (vincristine and vinblastine) were discovered to be amazing cancer-fighting medicines. They inhibit the growth of tumours very effectively.
Vinblastine has helped increase the survival rate of childhood leukaemia from 10% to 90%!
I learned this today visiting the Living Rainforest centre. The power of modern science to turn these natural compounds into life-saving drugs is truly humbling. It is also a reminder of the enormous important of biodiversity.
