This is something I have never thought of. Quite drastic!
Indeed!
"Deserts would cover North America, arid sand dunes would replace expanses of the Amazon rainforest in South America, and lush, green landscapes would flourish from central Africa to the Middle East, according to a computer simulation presented earlier this month at the annual European Geosciences Union General Assembly 2018 in Austria."

But why should it be reversed?

"Glories are common. They’re seen all the time by people traveling in airplanes. You need the sun to be directly behind your head. In front, you need an ordinary cloud. As you look toward the cloud, look for the shadow of the airplane. The plane’s shadow may be surrounded by a multi-colored circle of light. That’s the glory."
Not travelling much these days, but I shall watch out for them next time I am on a plane.

I've flown a lot, but didn't know about glories then: Real shame!
Neither did I.
Today is Pink Moon night!

This tells you when to se a Pink Moon in the USA. Not much help if you don't live in New York!
That´s true, DW. But we haven´t got telescopes anyway.

But you don't need a telescope to see the moon!
But one misses the details.

That video of the moon is very detailed, but am I being dense, I can't see that it is a Pink Moon.
Here is the explanation:
"What is a Pink Moon and when is the next full moon in March 2018?
Despite its name, don't be expecting a pink moon. This spectacle is named after the wildflowers which grow in the United States and Canada in the spring.
It's also known as the Egg Moon or Fish Moon, because of the shad fish that swim upstream at this time of year.
This moon is particularly important because it is used to fix the date of Easter, which falls on the first Sunday after the Pink Moon, and marks the start of the Jewish Passover.
In 2018, the pink moon rises at 2.37pm on March 31 - and Easter Sunday falls on April 1.

OK, so pink moon is not pink. Refers to flowers in Canada and USA. I've no idea when the Jewish passover is, either. I can see that all this is American influence on language. so I am slowly learning...

We haven't had anyone writing about globular clusters. Universe today does this so well. I've learned a lot about them in the article.
Yes, DW. I suppose the observation of them as of other Deep Sky Objects. has been improved by the arrival of better telescopes.
"In the 18th century, while searching the night sky for comets, French astronomer Charles Messier kept noting the presence of fixed, diffuse objects he initially mistook for comets. In time, he would come to compile a list of approximately 100 of these objects, hoping to prevent other astronomers from making the same mistake. This list – known as the Messier Catalog – would go on to become one of the most influential catalogs of Deep Sky Objects.
One of these objects is the globular cluster known as Messier 68. Located roughly 33,000 light-years away in the Constellation of Hydra, this cluster is orbiting through the Milky. In addition to being one of the most metal-poor globular clusters, it may be undergoing core collapse, and is believed to have been acquired from a satellite galaxy that merged with the Milky Way in the past."

DEAD STAR CIRCLED BY LIGHT
ESO
New data from the MUSE instrument on ESO's Very Large Telescope in Chile
have revealed a remarkable ring of gas in a system called 1E 0102.2-7219,
expanding slowly within the depths of numerous other fast-moving filaments
of gas and dust left behind after a supernova explosion that took place 2000
years ago in the Small Magellanic Cloud. That discovery allowed astronomers
to identify for the first time an isolated neutron star with low magnetic
field located beyond our own Milky Way galaxy. The team noticed that the
ring was centred on an X-ray source that had been noted years before and
designated p1. The nature of that source had remained a mystery. In
particular, it was not clear whether p1 actually lies inside the remnant or
behind it. It was only when the ring of gas -- which includes both neon and
oxygen -- was observed with MUSE that the scientific team noticed that it
perfectly circled p1. The coincidence was too great, and they realised that
p1 must lie within the supernova remnant itself. Once p1's location was
known, the team used existing X-ray observations of it from the Chandra
X-ray Observatory to determine that it must be an isolated neutron star,
with a low magnetic field. When massive stars explode as supernovae, they
leave behind curdled webs of hot gas and dust, known as supernova remnants.
Those turbulent structures are key to the redistribution of the heavier
elements -- which are cooked up by massive stars as they live and die --
into the interstellar medium, where they eventually form new stars and
planets. Typically barely ten kilometres across, yet with masses more than
our Sun's, isolated neutron stars with low magnetic fields are thought to be
abundant across the Universe, but they are very hard to find because they
shine only at X-ray wavelengths. The fact that the confirmation of p1 as an
isolated neutron star was enabled by optical observations is thus
particularly exciting.
