This tells you when to se a Pink Moon in the USA. Not much help if you don't live in New York!
Thatīs true, DW. But we havenīt got telescopes anyway.
But you don't need a telescope to see the moon!
But one misses the details.
That video was intended for post #1762:

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...
https://www.universetoday.com/37724/messier-68-1/
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.
Hubble detects helium in the atmosphere of an exoplanet for the first time
"Astronomers using the NASA/ESA Hubble Space Telescope have detected helium in the atmosphere of the exoplanet WASP-107b. This is the first time this element has been detected in the atmosphere of a planet outside the Solar System. The discovery demonstrates the ability to use infrared spectra to study exoplanet extended atmospheres."

I saw that post only today. Neutron stars, Helium, I wonder what more is coming.Quote:

Pros and Cons of Various Methods of Interstellar Travel
14 May , 2018 by Matt Williams
A new study by a UK scientists takes a look at the different means of interstellar travel, and considers the pros and cons of each.
Considering that the next star is right around the corner, amazing!
"[...]Dr. Braddock considers five principle means for mounting crewed missions to other star systems in his study. These include super-luminal (aka/ FTL) travel, hibernation or stasis regimes, negligible senescence (aka. anti-aging) engineering, world ships capable of supporting multiple generations of travellers (aka. generation ships), and cyogenic freezing technologies."

I am quite interested in the anti-aging part, but without having to travel for it. ;)

Aberdeen is one place I have seen the Northern Lights. Old Aberdeen to be more precise, where they have a song about "the Northern Lights of Old Aberdeen":
https://en.wikipedia.org/wiki/King%2...lege,_Aberdeen
"Survival is far from guaranteed. As the saying goes: space is hard. The first challenge will be switching on. The MarCO batteries were last checked in March by Tyvak Nano-Satellite Systems of Irvine, California, which inserted each CubeSat into a special dispenser that will propel it into space. Those batteries will be used to deploy each CubeSat’s solar arrays, with the hope that enough power will be left over to turn on their radios. If power is too low, the MarCO team may hear silence until each spacecraft is more fully charged.
If both MarCOs make the journey, they’ll test a method of communications relay that could act as a “black box” for future Mars landings, helping engineers understand the difficult process of getting spacecraft to safely touch down on the red planet."
http://earthsky.org/space/marco-cube...-new-comm-tech
Canīt say that looks very inviting but they are on it and will be improving fastly!
This one is related. But in fact, photos donīt do the Aurora borealis justice. On has to see the movements.
https://www.space.com/32610-amazing-...ures-2016.html
That is true, the Northern Lights we see from Old Aberdeen are less prominent than the shifting blue curtains of polar light!
King's College in Aberdeen was founded in 1495: https://en.wikipedia.org/wiki/King's...ge%2C_Aberdeen and also has the oldest endowed Chair of Medicine in Britain.
Scottish higher education has been pre-eminent from very early on, King's College was founded under a Papal Bull dated 10 February 1495.
I subscribe to EarthSky separately:http://earthsky.org/space/marco-cube...pale-blue-dot:
It seems that 2 cubesats are travelling to Mars, the first time that they are being employed beyond Earth:
"The Voyager 1 spacecraft took a classic portrait of Earth – the famous Pale Blue Dot image – from several billion miles away in 1990. On May 9, 2018, two tiny, boxy spacecraft known as CubeSats – nicknamed Wall-E and Eva by spaceflight engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California – took their own version of a pale blue dot image, capturing Earth and its moon in one shot.
This is the Mars Cube One or MarCO mission, launched on May 5 along with NASA’s InSight lander. InSight will touch down on Mars this November and study the planet’s deep interior for the first time."

Not strictly about Astronomy, but it does seem that opinion in Scotland do not want to leave the UK.

This post revealed to me much new information about Volcanoes
"Kilauea Volcano has been spewing lava and belching hazardous gases on Hawaii’s Big Island since early May, and the BBC reported on Sunday, May 20, 2018, that the situation for residents is “steadily worsening.” At the summit, a large explosion happened at around midnight on Friday night (May 18) into Saturday, sending a plume of volcanic gas some 10,000 feet (two miles, or 3 km) into the air. Early in the day on May 20, media outlets were reporting the first serious injury from Kilauea. Hawaii News Now reported:
The injured man was sitting on a balcony at his home when “lava spatter” – projectile molten rock – landed on him. “It hit him on the shin and shattered everything there down on his leg,” a spokeswoman for the county mayor said.
Lava spatters can weigh “as much a refrigerator,” she told Reuters.
The man has reportedly been hospitalized with serious injuries."

http://earthsky.org/space/asteroid-2...nent-immigrant
A new study has discovered the first known permanent immigrant to our solar system. The asteroid, currently nestling in Jupiter’s orbit, is the first known asteroid to have been captured from another star system. The new work is published in the peer-reviewed Monthly Notices of the Royal Astronomical Society: Letters.
The object known as ‘Oumuamua was the last interstellar interloper to hit the headlines in 2017. However, it was just a tourist passing through, whereas this former exo-asteroid – given the catchy name (514107) 2015 BZ509 – is a long-term resident.
It deserves a better name: (514107) 2015 BZ509 doesnīt have the necessary charm for headlines. I want to suggest ET1.
They won't change it, there must a reason for its length and complexity.

"The solar system just got a bit stranger. As astronomers continue their ongoing quest to find the elusive Planet Nine, a team found a space rock that lends credence to the idea that a huge super-Earth planet really exists in the outer reaches of our solar system.
The newfound asteroid, called 2015 BP519, adds to a growing body of evidence about little worlds in the solar system being perturbed by something big. Astronomers detailed its discovery and description in a new paper, adding that the bizarre angle of its orbit gives more weight to the idea that a big planet is out there — somewhere — tugging on the asteroid's path around the sun."
Its funny, isn't it that there is likely to be a big planet in orbit around our sun that we have not yet found!
I think the orbit is likely to be once every thousand years.
Amazing!
As I am also interested In Astrology I wonder how Astrology is dealing with this never ending discoveries. There Pluto is considered a planet as before and one related to very powerful events.
I've done a search in Universe Today - https://en.wikipedia.org/wiki/Universe_Today - for "Planet 9" and come up with many hits. It circles the sun far beyond the orbit of Neptune, so it is a Kuiper Belt object, and estimates of its orbit are well beyond every thousand years, so we really have no idea of its orbit. That is about the sum of our knowledge at this point. It is quite amusing that we know so little about this planet, given that we have a lot of indirect indications of its existence, and how far knowledge of near space has taken us.
From the astrological point of view that means that itīs position covers 10 to 11 generations. It changes only once each millennium. That is very slow indeed.PHP Code:estimates of its orbit are well beyond every thousand years
https://www.space.com/40650-astronom...net-rings.html
"Astronomers may have unknowingly discovered rocky planets with rings, which they mistook for other kinds of worlds, a new study finds.
Rings surround all this solar system's gas giant planets; they most famously wrap around Saturn, but also encircle Jupiter, Neptune and Uranus. In contrast, the solar system's rocky planets all currently lack rings.
However, rocky planets can have rings. For instance, Mars' moon Phobos might once have taken the form of rings around the Red Planet, the new study's author, Anthony Piro, an astrophysicist at the Observatories of the Carnegie Institution for Science in Pasadena, California, told Space.com. And as that moon gets closer to Mars over time, Phobos will likely get torn into a ring again "on a timescale of about 50 million years,"
Interesting post, DW. But, believe it or not, sometimes I long for old simple solar system with its moon and its sevenplanets.
Important!
Trump to Sign New Policy Directive Aimed at Commercial Space Regulation Reforms
"PASADENA, Calif. — A new policy President Trump will sign May 24 will implement a series of regulatory reforms to support commercial space recommended by the National Space Council earlier this year.
Space Policy Directive (SPD) 2, to be signed by the president at the White House, includes several sections to carry out streamlining of launch and remote sensing regulations, creation of a "one-stop-shopping" office for commercial space, and reviews of radiofrequency and export control policy"

What, not even Mars and its two moons? Or the many moons of our largest planet Jupiter?
Well, they are older discoveries. But I think the representation of the universe was more charming, when it was less cluttered. Just a bit "Little Prince" reasoning.
