An ''unusually calm and remote'' galaxy cluster was discovered 8.4 billion light-years away. (Sound like anyone you know?) Astronomers call it “relaxed,” meaning that it shows no signs of having been disrupted by violent collisions. go.nasa.gov/45cj0Af

are you guys into Project Hail Mary or what? Is it all the rage over there?


5 years ago today, NASA announced the first @Commercial_Crew assignments to fly to the @Space_Station on SpaceX and Boeing spacecraft.

In 2020, @NASA_Astronauts Doug Hurley and Bob Behnken became the first to be launched from US soil since the last space shuttle flight in 2011.

Welcome to Wildfires 101 🔥

Wildfires are an important part of many ecosystems, but climate change is causing fires to burn larger, longer, and more often. @nasa science helps us learn about and prepare for fires in a warmer world. go.nasa.gov/47iWmIA

The first spacecraft to orbit Mercury 🛰️

#OTD in 2004, the MESSENGER spacecraft launched to Mercury. It returned nearly 300,000 images over its 4 years in Mercury's orbit, revealing past volcanic activity and the presence of water ice.

Is climate change the same as global warming? Not quite.

The warming of Earth — or global warming — is just one factor that makes up a range of changes that are happening to our planet, which is climate change.

And @nasa is studying all of it: climate.nasa.gov/

A cluster of hundreds of galaxies that existed when the universe was 6.2 billion years old is a cosmic teenager known as “El Gordo” (Spanish for the “Fat One”). @NASAWebb took a look and discovered galaxies beyond and details within: go.nasa.gov/3YkoBCp

Another background galaxy magnified by El Gordo is the bright arc in Box B: El Anzuelo, or The Fishhook. Light from this galaxy took 10.6 billion years to reach Earth! Webb peered through its thick curtain of dust to observe star formation and the assembly of galaxies up close.
#JamesWebb


Take a closer look at one of the magnified background galaxies. The long thin line in Box A is known as La Flaca, or the Thin One. Webb used its infrared sensitivity to spot a red giant star within, the first star of this type observed beyond 1 billion light-years from Earth.

Youths!

Webb observed galaxy cluster El Gordo, a cosmic teen that existed 6.2 billion years after the big bang. The most massive cluster of its era, it’s a perfect gravitational magnifying glass, bending & distorting light from distant objects behind it: go.nasa.gov/3YkoBCp

What could be better than experiments in space? Experiments on the Moon!

#OTD in 1971, Apollo 15 astronaut David Scott performed his feather and hammer experiment on the Moon, demonstrating that without air resistance all objects fall at the same rate. go.nasa.gov/47cbHuk

My favourite moon experiment was when the new camera refused to work, so some highly trained for anything moonwalker hit it with a hammer, a very expensive camera, a very expensive hammer, and the best part is: the camera started to work!

Only its tripod was never designed to absorb such a blow, and I recall the crystal clear video slowly tilting over, coming to rest pointing directly at the sun for a brief moment before going permanently dark.

Anyone else remember this?

Fun fact - my first paper of my PhD featured El Gordo! We were also the first to spot the galaxy-galaxy lensed partial ring, which you can see toward the right of the image. We used Herschel and ALMA observations, so we mostly saw the dust and gas rather than stars, but it's still a wonderful massive merging cluster.
