Did European Colonisation precipitate the Little Ice Age?

Many of us think that rapid environmental change is a quintessentially modern crisis. Today, temperatures are soaring, topsoil is washing away, phosphorous is being diluted, forests are retreating, pesticides are sterilising farmland, fertilisers are choking waterways, and biodiversity is plummeting under the onslaught of overpopulated, industrialised societies. Some of these changes are indeed truly new. But many others have deep roots and distant echoes in the early modern period, the years between around 1400 and 1800 when much of the world began to assume its present form. Recently, scientists, geographers, historians, and archaeologists have combined expertise and evidence to reveal just how profound early modern environmental transformations really were.

Brazilian Couple Plants 2 Million Trees [and Creates a New Forest!]

In the early 2000s, famed Brazilian photographer Sebastião Salgado and his wife Lélia Wanick decided to rebuild their deserted piece of land of 600 hectares in Aimorés, Brazil. They planted more than 2 million tree saplings in 18 years.

And the result is amazing! They created a new forest, and now, the site has 293 plant species, 172 bird species, and 33 animal species, some of which were on the verge of extinction.

What high-speed astronomy can tell us about the galactic zoo

For most of human history, the distant ‘celestial sphere’ was regarded as perfect and unchanging. Stars remained in place, planets moved predictably, and the few rogue comets were viewed as atmospheric phenomena. This began to change with the Danish astronomer Tycho Brahe’s observation of the supernova of 1572 – apparently, a new star – and his studies of the Great Comet of 1577, which he proved was actually a distant object. Nonetheless, the impression of permanence is strong. There are very few astronomical objects that noticeably vary to the naked eye: only the brightest comets, novae, and supernovae. For observers in the northern hemisphere, the last naked-eye supernova was in 1604.

First-ever image of a Black Hole

This is the first image ever of a black hole. The EHT (Event Horizon Telescope) captured an image of the nearby elliptical galaxy Messier 87’s (M87’s) supermassive black hole in the center of the Virgo galaxy cluster, 53 million light-years away. It was revealed today (April 10, Wednesday) in multiple press conferences around the world, and was the result of a global collaborative effort from over 200 scientists working with the EHT.
