A giant iceberg, about twice the size of Chicago, broke off from Antartica’s Brunt Ice Shelf in late February 2021.
Satellite images show the iceberg breaking free and moving away rapidly from the floating ice shelf. Image via ESA
A new study suggests that spring snowmelt in the Alps is occurring earlier in the year, and the earlier warming – due to climate change – threatens vitally important microbial communities in alpine soils.
Scientists examined rock cores taken from the Chicxulub crater in Mexico, site of the asteroid impact that triggered dinosaur extinction, and found iridium, a telltale sign of asteroids.

A new study suggests that the Gulf Stream – an Atlantic Ocean current that plays a large role in shaping Earth’s weather patterns – is weaker now than at any point in the last 1,000 years.
The Gulf Stream plays a vital role in redistributing heat throughout our planet's climate system. This animation shows the Gulf Stream sending warm water to the North Atlantic Ocean, forcing colder water to sink and travel southward.

Cloud streets are a manifestation of Earth’s atmosphere in motion. They’re normally seen by satellites looking down on Earth, but sometimes they can be seen from the ground as well. See cool images here!
NASA has selected 16 cool new futuristic space technology concepts for further study. Four of them are from NASA’s own Jet Propulsion Laboratory (JPL), including a railway system on the moon to move cargo.
One of the new proposals from JPL is FLOAT, where a railway system would be used on the moon to move cargo. Magnetic robots would levitate over the track. Image via Ethan Schaler/ NASA
Meet the nano-chameleon, a new contender for the title of world’s smallest reptile
With a body size of just 0.53 inches (13.5 mm), this nano-chameleon (Brookesia nana
) is the smallest known male of the roughly 11,500 known reptile species. Image via Frank Glaw
March 2021 features 4 bright planets! Mars is the only one to shine in the evening sky. Mercury, Jupiter and Saturn all appear in the east before sunrise. Venus – the brightest planet – hides behind the sun this month.
View larger. | V. Srinivasagopalan caught both Venus (below) and Jupiter on September 22, 2018 from Bangalore, India. Remember, Venus is going into the sunset in October, 2018. Watch for it soon!
A mammoth tooth uncovered from the Siberian permafrost yields the oldest DNA yet discovered and provides insight into the evolution of the giant beasts.
