Baby stars!

This galaxy might be bursting with star formation and stellar newborns.

Our @NASAHubble space telescope turned its powerful eye towards galaxy NGC 3749,
over 135 million light-years away from Earth.
This galaxy shows strong emission lines (signs of emission from elements within a galaxy's spectrum of light),
suggesting that it has plenty of star-forming material and energetic new stars.
⁣
⁣
This study technique,
known as spectroscopy,
is used by astronomers to understand a galaxy’s type and composition,
the density and temperature of any emitting gas,
the star formation rate,
or how massive the galaxy’s central black hole might be.

Did this debris shield spark joy?⁣
⁣
Sometimes you need to let go of what no longer serves you!⁣
⁣
On the first spacewalk to repair the International Space Station's cosmic particle detector,
@AstroDrewMorgan and @europeanspaceagency astronaut Luca Parmitano removed a debris shield to access the work site.
It was too big to take inside,
so the best option was to jettison it behind @iss,
where it will disintegrate in the upper atmosphere.
This video was taken on Nov.

On Friday,
Nov.
22,
the two astronauts will once again venture into the vacuum of space to resume repair work on the particle detector,
called the Alpha Magnetic Spectrometer.

It may look like a veiny eyeball,
but Jupiter's moon Europa is more than meets the eye.
👁️⁣
⁣

For the first time,
scientists have detected water vapor above the icy moon's surface,
giving us further evidence that oceans of liquid water may exist beneath Europa's crust.
⁣
⁣
💧
Water is one of the main ingredients necessary for life,
making Europa an alluring destination for exploration.
Scientists will soon be able get close enough to this intriguing moon to settle their lingering questions.
The Europa Clipper mission,
expected to launch in the mid-2020s,
will survey the moon up close and sample molecules in its atmosphere.⁣
⁣
Seen here is a view of Europa made from images taken by the Galileo spacecraft in the late 1990s during a flyby.
