Thanks.
What occurs at 1420 MHz (other than wow signals !) ?
Its the radio frequency that hydrogen naturally emits, some guy came up with a theory a couple of years ago that it was a comet.

HYDROGEN LINE OBSERVATIONS OF COMETARY SPECTRA AT 1420 MHZ
ANTONIO PARIS
THE CENTER FOR PLANETARY SCIENCE
ABSTRACT
In 2016, the Center for Planetary Science proposed a hypothesis arguing a comet and/or its hydrogen
cloud were a strong candidate for the source of the “Wow!” Signal

shithole


Two astronomical observatories in Mexico have scaled back access and operations because of security threats, Mexico’s National Institute of Astrophysics, Optics and Electronics (INAOE) in San Andrés Cholula announced on 5 February. The Large Millimeter Telescope (LMT) and the High-Altitude Water Cherenkov Gamma-Ray Observatory (HAWC) are both located on the Sierra Negra volcano in the Mexican state of Puebla. The highway leading to the mountain has become a target for carjackings and robberies in recent weeks, as a fight intensifies between the Mexican government and fuel thieves. Scientists and technical staff have stopped visits to the HAWC, canceling a planned repair trip, while the LMT has reduced its scientific operations to “the bare minimum level,” says INAOE astrophysicist and LMT Director David Hughes. “I cannot responsibly continue the scientific operation of the telescope until these issues are addressed.

NASA regrets to announce that Mars Opportunity has passed away. After falling into a coma in June 2018 it succumbed to energy loss and hypothermia and was pronounced dead February 12, 2019.


Opportunity had an unusually long life, exceeding the anticipated four score and ten days by fifteen years. A peripatetic wanderer, the 185 kg Opportunity ambled vast distances, covering 45 km despite a slow pace of about 1 cm/s. Often cold, Opportunity's heaters and radioisotope generator kept it comfortable most days. An intellectual lightweight, its 20 MHz brain proved more than adequate to assist Opportunity in its leisurely promenade.


Late in life Opportunity suffered from progressive dementia which no medical ministrations could halt. It was eventually only able to keep short-term memories when engineers found flash failures and redirected experiences into RAM.


Opportunity received many accolades, perhaps the most enduring was the naming of asteroid 39382 Opportunity in its honor.


Opportunity was predeceased by sibling Spirit in 2011. It is survived by Mars Curiosity.


NASA and the engineering community mourns its passing but acknowledges the great science Opportunity beamed down for so many years. Donations for successor rovers will be sent to the Internal Revenue Service.

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.
It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".
The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world.
Details have been published today in Astrophysical Journal Letters.

Can we send a team up from health and safety to put a fence or handrail round it, or something?

Horsemanure.
I agree with you FM, this seems to be a case of "Life imitating Sci-Fi(art)". All this is fluff in the sky.Human beings can never travel to and live on these "planets".The human body is a organism designed to live on earth-like bodies reachable within few years(5 let's say for argument).The damage done to the body for years in a weightlessness atmosphere cannot be underestimated.The muscles around the vital organs would fail and the bones would weaken and lose their strength.The blood pressure would go "haywire" as the pumps from the heart would be confused by the lack of gravity etc.I have to be convinced, but you know these mad scientists type , they can pull the wool over any govt/private agency eyes involved in the "Space Industry".

This investigation is rather expensive horse manure at I believe 30million plus euro.
It really doesn’t matter how black holes behave around the event horizon.

To spend that sum on concocting a crappy photo of a distant object illustrates how skewed the priorities of many are.

Yes and no.

For the Earth to exist, it is contingent, highly contingent actually, on all matter and all space, throughout the Universe.
If for example Jupiter didn't exist, Earth's existence would not be possible.

So whether we like or not, what's "out there" has huge bearing on "in here".

I agree that €30 million is a huge sum of money and the value of getting a photo of a black hole should be questioned.

Has everybody forgotten the Black Hole in Calcutta?
A far more serious and life threatening affair.
I don’t think there are any photos of that Black Hole but there are personal accounts that give far more detail than that grossly over rated and over priced montage you post above.
