This may be Hubble’s last photo, but also one of his best.

Hubble is still active around the Earth, and the Space Telescope, which is in its last moments, takes advantage of the moment to feast on new pictures.

While much of the space news is on the JWST, the latter would almost make us forget that there is another space telescope in our celestial vault and the latter is still active, although it is no longer near the end than the beginning. But while many seem to want to condemn it before its official end, the telescope still has its objectives and it is still able to scan the sky for wonders.

He has just taken a more than successful snapshot of a nebula, very difficult to see from Earth as the light that reaches us is so thin. Called the Shrimp Nebula, the latter is found in the constellation Scorpio. It is located more than 6000 light years from us, which is actually not very far given the immense dimensions of the Universe.

Star nurseries

Nebulae are veritable star nurseries, areas of the sky where the density of matter is such that luminous stars are formed there by the thousands. These are actually large clouds of gas that form as a result of a massive star explosion. Once the immense star has rejected its material, the latter diffuses into space offering immense and magnificent shades of color.

Like a cycle of life, it is from the death of this immense star that other small stars will feed on to see the light of day and shine in their turn. Stretching over 250 light years across, it is considered one of the most prolific nurseries for stoles that we know of today.

An emission nebula

This nebula also offers the particularity of being “emission” according to the official name of NASA. Without going into overly technical details, this means that the nebula’s gases have been energized or ionized during their journey through the vacuum of space, certainly by radiation from neighboring stars. The latter are therefore charged with electrons which then roam the Universe, some even reaching us in the form of infrared radiation.

The latter is precisely the preferred working point of the James Webb Space Telescope. He, whose departure is scheduled for the end of the year, will therefore be able to resume Hubble’s work and complete them by adding the ionic radiation perceptible in the infrared.
