Scientists observing the occultation could get more detailed and accurate measurements of the asteroid’s size and insight into what’s happening with Betelgeuse, which suddenly dimmed in 2019 ...
An asteroid the size of a small truck will pass by Earth tonight, making one of the closest approaches to the planet ever recorded. Asteroid 2023 BU will zoom over the southern tip of South ...
A potential "statewide extinction event" puts the 126 (and all of Texas) in danger when the Fox drama returns for its final four episodes. Yes, an asteroid is headed to “9-1-1: Lone Star ...
They proposed that the Chicxulub asteroid was also a member of this group. [69] Subsequent evidence has disproven this theory. A 2009 spectrographic analysis revealed that 298 Baptistina has a different composition more typical of an S-type asteroid than the presumed carbonaceous chondrite composition of the Chicxulub impactor. [70]
This list includes few examples since there are about 589 asteroids in the asteroid belt with a measured radius between 20 and 49 km. [171] Many thousands of objects of this size range have yet to be discovered in the trans-Neptunian region.
Sirius is the brightest star in the night sky.Its name is derived from the Greek word Σείριος (Latin script: Seirios), meaning lit. 'glowing' or 'scorching'. The star is designated α Canis Majoris, Latinized to Alpha Canis Majoris, and abbreviated α CMa or Alpha CMa.
The impact site was not examined by scientists until 20 years later, when they discovered the asteroid carved a massive area of destruction of around 830 square miles, according to NASA.
Radio-telescope images taken in 1998 confirm that Betelgeuse has a highly complex atmosphere, [158] with a temperature of 3,450 ± 850 K, similar to that recorded on the star's surface but much lower than surrounding gas in the same region. [158] [159] The VLA images also show this lower-temperature gas progressively cools as it extends outward ...
