Scientists made models for TRAPPIST-1 b: with an atmosphere and without. @NASAWebb's measurements matched the model for a planet without atmosphere. This bodes well for Webb's ability to study temperate, Earth-size planets, like other TRAPPIST-1 worlds. go.nasa.gov/42VAWiu
#NASAExoplanets


Our first look at a TRAPPIST-1 planet with @NASAWebb reveals the innermost world’s dayside temperature of about 450 degrees F (232 C) and suggests it has no significant atmosphere. It's the first direct measurement of *any* light from a rocky exoplanet. go.nasa.gov/42VAWiu

One week until you meet the astronauts flying to the Moon aboard the #Artemis II mission!

The @NASA_Orion spacecraft will return to the Moon — this time, with four astronauts aboard. Set a reminder for April 3 for the reveal: youtube.com/live/mua1Lysc_JQ?s…

A low-pressure system lifted sand and dust from the Gobi Desert in late March, causing a major dust storm across Mongolia and China.

A recent @nasagoddard study found that high levels of the air pollutant PM2.5 likely contributed to 2.89 million premature deaths, of which 22% were linked to dust.

Depending on the size and type of particles and where they reach in the atmosphere, dust can contribute to warming or cooling, and influence storms and weather events.

TRAPPIST-1 b: We give it a one (M-dwarf) star review; it lacks atmosphere. ⭐

Webb found the dayside temperature of this rocky exoplanet to be about 450º F (227º C) — suggesting it has no significant atmosphere: go.nasa.gov/3K9cS4g

Here’s why this is a big deal ⬇️
#JamesWebb



Scientists made models for TRAPPIST-1 b: with an atmosphere, and without. Webb’s results matched the model with no atmosphere. If TRAPPIST-1 b did have an atmosphere to circulate and distribute heat, its temperature should have been much cooler than what was measured.
#JamesWebb


How do you take a planet’s temperature? The team measured the change in brightness (in infrared light, or emitted heat energy) when TRAPPIST-1 b moved behind its star. This was a challenge because the star is 1000 times brighter, and the change in brightness was less than 0.1%.
#JamesWebb

At first glance, this image may appear to be a view of stars. Rather, almost all these different colored dots are black holes or entire galaxies. When we add sound, we can hear the data. Music represents the full range of X-ray frequencies collected by @chandraxray.

Just like in "Dirk Gently's Holistic Detective Agency"!


The central region of this image contains an incredible concentration of supermassive black holes, equivalent to about 5,000 objects that would fit into the area on the sky covered by the full Moon. Complete visual description of the Chandra Deep Field: chandra.si.edu/photo/2021/soni…

Most landscapes in North America are fire-adapted, and frequent fires enable trees and wildlife to flourish.

Prescribed (or controlled) burns are often used to manage forests and forest undergrowth.
