Tonight, count the stars and remember a trailblazer.
We’re saddened by the passing of celebrated #HiddenFigures mathematician Katherine Johnson. She passed away at 101 years old.
An America hero, Johnson’s legacy of excellence broke down racial and social barriers while helping get our space agency off the ground.
Once a “human computer”, she famously calculated the flight trajectory for Alan Shepard, the first American in space.
And when we began to use electronic computers for calculations, astronaut John Glenn said that he’d trust the computers only after Johnson personally checked the math.
As a girl, Katherine Johnson counted everything. As a mathematician, her calculations proved critical to our early successes in space travel.
With slide rules and pencils, Katherine Johnson’s brilliant mind helped launch our nation into space. No longer a Hidden Figure, her bravery and commitment to excellence leaves an eternal legacy for us all.
“We will always have STEM with us. Some things will drop out of the public eye and will go away, but there will always be science, engineering and technology. And there will always, always be mathematics.” - Katherine Johnson 1918 -2020
May she rest in peace, and may her powerful legacy inspire generations to come! What does Katherine Johnson’s legacy mean to you? Share in the comments.

Comet G3 ATLAS: a Tail and a Telescope Image Credit & Copyright: Yuri Beletsky (Carnegie Las Campanas Observatory, TWAN)
Explanation: Comet C/2024 G3 ATLAS has made a dramatic appearance in planet Earth’s skies. A visitor from the distant Oort Cloud, the comet reached its perihelion on January 13. On January 19, the bright comet was captured here from ESO Paranal Observatory in the Atacama desert in Chile. Sporting spectacular sweeping dust tails, this comet ATLAS is setting in the southern hemisphere twilight and was clearly visible to the unaided eye. In the foreground is the closed shell of one of the observatory’s famous auxiliary telescopes. Still wowing southern hemisphere observers, the comet’s bright coma has become diffuse, its icy nucleus apparently disintegrating following its close approach to the Sun.

The Long Tails of Comet NEOWISE Image Credit & Copyright: Petr Horalek
Explanation: This Comet NEOWISE (C/2020 F3) now sweeps through our fair planet’s northern skies. Its long tails stretch across this deep skyview from Suchy Vrch, Czech Republic. Recorded on the night of July 13/14, the composite of untracked foreground and tracked and filtered sky exposures teases out details in the comet’s tail not visible to the unaided eye. Faint structures extend to the top of the frame, over 20 degrees from the comet’s bright coma. Pushed out by the pressure of sunlight itself, the broad curve of the comet’s yellowish dust tail is easy to see by eye. But the fainter, more bluish tail is separate from the reflective comet dust. The fainter tail is an ion tail, formed as ions from the cometary coma are dragged outward by magnetic fields in the solar wind and fluoresce in the sunlight. Outbound NEOWISE is climbing higher in northern evening skies, coming closest to Earth on July 23rd.
