How big is the blue whale? Watch to see

The blue whale (scientific name: Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). Up to 31 meters (102 feet) in length and 190 tonnes (210 short tons) in weight, it is the largest extant animal and also is the heaviest known to have existed. But it’s hard to conceptualize how big these wonderful animals really are. To put things into perspective, Facts in Motion channel prepared a video titled “Blue Whales Are Way Bigger Than You Think”. The video also explains the evolutionary reasons behind how and why blue whales get that large.

Watch: What happens to old spacecraft?

Since the launch of the first artificial Earth satellite, Sputnik 1, on October 4, 1957, we launched thousands of spacecraft into Earth orbit and beyond. A fraction of them are still functioning, but what happened to the vast majority of them? “The Curious Droid” published another informative video titled “What happens to old spacecraft?”

Driving Distances on Mars and the Moon: Out-of-This-World-Records

This chart, prepared by NASA illustrates comparisons among the driving distances by various wheeled vehicles on the surface of the planetary bodies other than Earth (as of February 13, 2019, only the moon and Mars). Opportunity rover, which declared dead after record-breaking 15-years on the Martian surface also holds the off-Earth roving distance record after accruing 45.16 kilometers (28.06 miles) of driving on Mars.

Opportunity Rover’s first and last images from the Martian surface

The first and the last images of NASA’s Opportunity rover from the Martian surface. The first photo (on the left) was acquired on Sol 1 (at approximately 14:58:27 Mars local solar time on January 25, 2004). The last photo (on the right) was taken on Sol 5111 (on June 10, 2018 ), before the rover entered hibernation due to a huge dust storm.

Watch – NASA Explorers: Permafrost

In this episode of NASA Explorers (Season 1 Episode 7), the scientists go back in time – by going underground. In the Arctic, a frozen layer of soil – permafrost, the “permanently” frozen earth – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane – two harmful greenhouse gases which contribute to global warming.
