99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
In a bit of ominous news befitting a Friday the 13th: It turns out that the asteroid Apophis could have a very small chance of colliding into Earth in five years, when it is expected to make a ...
Apophis to make 2029 flyby to Earth. Apophis is projected to pass within 20,000 miles of our planet’s surface on April 13, 2029. For the superstitious lot, yes, that's a Friday, no less.
There are 24 known species in seven genera. [ 2 ] [ 3 ] These include, for instance, Abyssocottus korotneffi and Cottinella boulengeri which are among the deepest-living freshwater fish . [ 5 ] Baikal is the deepest lake on Earth (1,642 m or 5,387 ft) and sculpins occupy even its greatest depths.
This would have the opposite effects: expand the area available for tropical species; kill temperate species or force them to migrate towards the poles; possibly cause severe extinctions of polar species; often make the Earth's climate wetter on average, mainly by melting ice and snow and thus increasing the volume of the water cycle. It might ...
The type species, D. terrelli, is the largest, best-known species of the genus. Size estimates for this species range from 4.1–10 m (13–33 ft) in length, though estimates greater than 4.5 m are poorly supported. [4] [2] Skulls of this species can be up to 60–70 cm (24–28 in) in length. [2]
The adults of some species, such as Kryptolebias marmoratus, can additionally survive out of the water for several weeks. [3] Most killifish are small, measuring from 2.5 to 5 centimetres (1 to 2 in), with the largest species growing to just under 15 centimetres (6 in).
Scientists saw a male orca kill a juvenile great white shark within minutes last year. The hunting behavior could be a sign of a wider shift in the marine ecosystem.
