After years of preparatory studies, we are formally starting an astrophysics mission designed to help unlock the secrets of the universe.
With a view 100 times bigger than that of our Hubble Space Telescope, WFIRST will help unravel the secrets of dark energy and dark matter, and explore the evolution of the cosmos. It will also help us discover new worlds and advance the search for planets suitable for life.
WFIRST is slated to launch in the mid-2020s. The observatory will begin operations after traveling about one million miles from Earth, in a direction directly opposite the sun.
Telescopes usually come in two different “flavors” - you have really big, powerful telescopes, but those telescopes only see a tiny part of the sky. Or, telescopes are smaller and so they lack that power, but they can see big parts of the sky. WFIRST is the best of worlds.
No matter how good a telescope you build, it’s always going to have some residual errors. WFIRST will be the first time that we’re going to fly an instrument that contains special mirrors that will allow us to correct for errors in the telescope. This has never been done in space before!
Employing multiple techniques, astronomers will also use WFIRST to track how dark energy and dark matter have affected the evolution of our universe. Dark energy is a mysterious, negative pressure that has been speeding up the expansion of the universe. Dark matter is invisible material that makes up most of the matter in our universe.
Single WFIRST images will contain over a million galaxies! We can’t categorize and catalogue those galaxies on our own, which is where citizen science comes in. This allows interested people in the general public to solve scientific problems.

My brother and I saw this precious little rat snake watching everyone gardening in my grandparents’ yard. How could anyone hate this sweet curious face? I was cooing at him for like 20 minutes ♥️
Quando vejo esta linda arte meu coração e razão se enfurece com os professores, pois um dia falaram que os povos africanos não tinham arte e nem história.

Study Examines Religious Experiences and Depression
While attending religious services is generally associated with improvements in mental wellbeing, a new study reports spiritual experiences and belief in divine leading can lead to an increased risk of depression, especially in men.
Incomprehensible: The Scale of The Universe
Meet the real women behind Hidden Figures.
In the early days of the Space Race, Dorothy Vaughan headed the National Advisory Committee for Aeronautics’ (NACA) West Area Computing unit. It was an important but segregated unit of mostly female mathematicians doing aerospace calculations by hand. When NACA became NASA in 1958, the Analysis and Computation Division desegregated and Vaughan became a sought-after expert on FORTRAN – a programming language used on IBM mainframes.
Vaughan is one of the women whose work inspired the film Hidden Figures — a true story of three African American mathematicians who helped NASA launch the first Americans into space.
