Are the colours in astronomical images real? What do these colours mean? And what about images that aren't taken in visible light?

We get these questions all the time, so in the latest episode of Chasing Starlight we show you how these colourful images are made:

NASA's Parker Solar Probe has set a new record as the fastest object ever built, hitting a velocity of 394,736 mph (635,266 kph) relative to the Sun.

That's about 300 times as fast as a speeding bullet. Damn!

For a dose of perspective: Even at the peak speed of the Parker Solar Probe (~180 km/sec), it would take more than 7,000 years to reach Alpha Centauri, the nearest star system.

Interstellar distances are HUGE.

#Euclid has hardware, software, data, and functional contributions by more than 100 institutions across #ESA member states, the USA, Canada, and Japan.

With the fully assembled #satellite currently undergoing final tests, and with the science computing ground segment on it's home stretch, we're seeing Euclid rapidly turning from hard- and software into a soon flying #astronomy data-producing #space mission!

No new info on the status of the Voyager 1 spacecraft, which since Sep 2023 has been sending a 1010 bit pattern instead of real data.

Several popular science outfits have been covering it lately. A bit flip in the FDS is suspected, but it is difficult to identify since the memory cannot be read back.

Several commands were sent yesterday to Voyager 1; responses will arrive 45 hours later tomorrow.

Wonder why they cannot overwrite all prog and data memory.

I've been listening to season 6 of NASA's Curious Universe podcast. So far there are 5 episodes, all of them really good!

You've heard of a sound echo: Sound bounces off of a surface and reflects back, causing a delay.

Did you know that light echos are also a thing? If there is a flash of light from something like a supernova, that light can hit interstellar clouds of dust and then reflect back, giving you light from the original supernova but on a delay.

We can use this delayed light to learn about what kind of star blew up in the supernova.

Happy first anniversary, #NASAWebb! One year after beginning science operations, Webb is celebrating with a highly detailed image of the closest star-forming region to Earth. Peer deeper in the cloud: https://webbtelescope.pub/3JUoBTA

#NASAWebb researchers have made major strides in confirming the source of dust in the early universe with observations of two dying stars (supernovas!): https://webbtelescope.pub/3CRzTnL

Thought for the weekend:
Our eyes are narrowly adapted to conditions on Earth. To see reality as it truly is, we have to use instruments that go far beyond the limits of human vision.
These images merge visible light with infrared & x-rays to show a bigger universe:

I was a NASA intern in the '80s when I heard that astronomers had discovered a mysterious disk around the nearby star Fomalhaut.
Now JWST has revealed exactly what they are: three enormous, dusty asteroid belts around another star!

The first #NASAWebb results from TRAPPIST-1 are in! Measurements of mid-infrared light from TRAPPIST-1 b indicate that the rocky Earth-sized planet is hot enough to bake pizza and is probably devoid of atmosphere. What does this mean? ➡️ https://webbtelescope.pub/3nlCcLc
