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

Class 0 protostar / nascent star / newborn star / Herbig-Haro object >

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.

star > Trappist-1 USA

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.

Hunting for a Giant Black Hole, Astronomers Found a Nest of Darkness

No Gargantua dwells at the heart of stellar cluster NGC 6397.

Instead, a few dozen smaller black holes seem to be swarming around in there,
