Omega Centauri
is a globular cluster located in the
constellation of Centaurus
about 15,800 light years from Earth.
Globular clusters consist of very old stars
with the stars in Omega Centauri
estimated to be more than
11bn years old.
There are more than 10m stars
in this cluster all gravitationally interacting with each
other
Shooting for the stars:
the otherworldly art of
astrophotography – in pictures
From deep in the bush just outside Bathurst in Australia,
Rodney Watters and Niall MacNeill bring the darkness of space
into the light.
Using an alchemy of high-speed cameras, telescopes and computer processors,
the images created for their new book overcome the multitude
of challenges
involved in capturing celestial bodies light years away

Herbig-Haro 211 (HH 211)
USA
A new image from NASA's
James Webb Space Telescope
has captured what Earth's sun looked like
when it was only
a few tens of thousands of years old.
The image of Herbig-Haro 211 (HH 211),
released by NASA on Sept. 14,
shows the outflow of a young star.
"An infantile analogue of our Sun,"
NASA said in a statement.
Located about 1,000 light-years
from Earth in the constellation Perseus,
HH21 has only about 8% of the Sun's mass.
A Class 0 protostar,
meaning the nascent star
is less than 100,000 years old,
"eventually will grow into a star like the Sun,"
Webb Space Telescope wrote on its website.

massive star > Earendel
UK
Scientists estimate that Earendel,
whose name means “morning star” in Old English,
is at least 50 times the mass of the Sun
and millions of times as bright,
placing it among the most massive stars known.
But even such a brilliant star
would not normally be detectable.
At such vast distances,
even an entire galaxy is just a smudge of light.
It was only thanks to natural magnification
by a huge galaxy cluster, WHL0137-08,
which sits between us and Earendel,
that astronomers were able to make the detection.
The cluster’s gravitational pull is so intense
that light bends around it,
creating a powerful cosmic magnifying glass
that amplifies light from distant objects lying behind it.
Scientists calculate
that Earendel’s brightness
is magnified by a factor of thousands
– a situation that may not be repeated
with other ancient stars within our lifetimes.
“This might be the earliest star
we will ever see since the big bang,”
said Dr Guillaume Mahler,
an astronomer at Durham University and co-author.
The star’s distance was estimated by its colour.
Light is “red-shifted” away from its original wavelength
as it travels through the expanding universe and so,
although Earendel would have been blue if seen from nearby,
12.9bn years ago,
it appears a deep red in the Hubble images.
The observations have been hailed as hugely significant
and been prioritised for the first cycle of observations
using Nasa’s James Webb Space Telescope,
due to begin in June.
This will allow scientists to definitively confirm
that they are looking at a single, very distant star.
An alternative possibility, deemed very unlikely,
is that it is a dim, nearby brown dwarf.

Trappist-1 is a small, cool star,
its habitable zone is closer to it
than in our own solar system.
As a result,
its potentially habitable planets
orbit at close range,
taking just a few days
to circle the star.
