M42: Inside the Orion Nebula
Image Credit: R. Villaverde, Hubble Legacy Archive, +NASA

The Great Nebula in Orion, an immense, nearby starbirth region, is probably the most famous of all astronomical nebulas. Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away. In the above deep image composite in assigned colors taken by the Hubble Space Telescope wisps and sheets of dust and gas are particularly evident. The Great Nebula in Orion can be found with the unaided eye near the easily identifiable belt of three stars in the popular constellation Orion. In addition to housing a bright open cluster of stars known as the Trapezium, the Orion Nebula contains many stellar nurseries. These nurseries contain much hydrogen gas, hot young stars, proplyds, and stellar jets spewing material at high speeds. Also known as M42, the Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.

 Please read crewmates instead of cremates 
Astronaut Mike Hopkins aboard the International Space Station tweeted this image of the aurora in the Southern Hemisphere earlier this
evening, saying the "southern lights were absolutely stunning tonight!" On the #ISS on Thursday, more CubeSats were deployed, while the crew prepped for the arrival of a cargo craft and the departure of three cremates.

On this day in 1968 the Apollo 6 mission was launched at Kennedy Space Center in Florida.

The 10-hour unmanned mission tested elements of the mission, Apollo 10, that took humans to and from the moon the following year - namely, the Saturn V rocket and the Command, Service and Lunar Modules.

Apollo 6 did not achieve its objective of placing the Command/Service Module in an orbit that could reach the Moon, but it did give NASA confidence in the Saturn V.

Did he predict that?

Congratulations to Princeton University's Yakov Sinai. The mathematician has been awarded one of the biggest prizes in mathematics: Norway's Abel Prize.
Sinai has created bridges connecting the world of deterministic (dynamical) systems with the world of probabilistic (stochastic) systems.

Cusp momentum: today, the center of the Sun has been directly above the Earth’s equator at approximately at 16:57 UTC, marking the vernal equinox.
On the equinox, night and day are nearly exactly the same length – 12 hours – all over the world. This is the reason it's called an equinox, derived from Latin, meaning equal night.
In the northern hemisphere is the first day of spring, while in the southern it is the first of autumn. In the northern hemisphere the March equinox marks the start of spring and has long been celebrated as a time of rebirth. 

The equinoctial point, where the celestial equator and the Earth's ecliptic intersect, is not stable. It shifts around the ecliptic continuously, during one cosmic year, otherwise known as Platonic year, which is about 25.920 Julian years. Each Platonic year is divided into 12 parts, each of 2160 years ( Messianic cycle ).

The equinoxes are mystical times since the ancient worlds, when initiations and great mysteries were celebrated. It is believed that on the night of equinox, heavens open for contemplation of that state of existence beneath the observable.

So we shall close our eyes to see and shut the ears to hear...

His birthday

It's the birthday of Antoine Becquerel, who was born in 1788 in Châtillon-Coligny, France.
After fighting for France in the Peninsular War, Becquerel became a scientist whose research interests were diverse.
He studied the electrical properties of materials, invented the differential galvanometer and discovered a photoelectric effect.
He was also interested in biophysics and meteorology.
Becquerel's son, Edmond Becquerel, and his grandson, Henri Becquerel, were also physicists.

The becquerel (defined as the activity of a quantity of radioactive material in which one nucleus decays per second)  unit is named after Henri Becquerel,  a Nobel laureate  and the discoverer of radioactivity.

My pleasure +Rajini Rao! :-) 
It is true that the best known is Henri Bequerel.

Today In History

On 23 February 1927 Werner Heisenberg (right) wrote a 14-page letter to Wolfgang Pauli (left) describing the uncertainty principle. The letter would later form the basis of Heisenberg's famous paper, Über den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik  (On the perceptual content of quantum theoretical kinematics and mechanics).

'Day is dawning in quantum theory' replied Pauli ...
