Is anyone trying to observe the transit of Mercury? Here in Manchester it's wonderfully sunny, but windy, so much so that both my binoculars and the bit of paper I was trying to project the sun onto were shaking and flapping like mad. Still, I made out a wee dot. I'll try again later at home, I have a bracket to hold binoculars on a tripod somewhere.

Yes its a little windy but here's my attempt with an old spotting scope, You can just make it out off centre to the lower right. The faint spot off centre to the upper left is a sunspot.

I'm exploiting the parents service's every hour or two in marking the transit time using projection, helps having a extra pair of hands and thankfully the wind has settled down here a little in allowing more stable observing.

We're hosting an AMA on /r/science that might be of interest here:

Science AMA Series: I’m Dr. Patrick McCarthy, interim president for the Giant Magellan Telescope. I’m leading the team building the world’s largest telescope. AMA!

Hi Redditors, I’m Pat McCarthy, and I’m looking forward to talking about life as a working astronomer with you! A little about me: I’m best known for my work observing the formation of the earliest galaxies and my study of distant low frequency cosmic radio sources. In the late 1990s, my colleagues and I were among the first to explore the distant universe – galaxies and quasars more than halfway back towards the big bang!
I joined the Carnegie Observatories as a Carnegie Fellow in 1988, after completing my PhD at the University of California at Berkeley. In 1991, I received the Hubble Fellowship, during the second year of its program and I joined the faculty at Carnegie in 1993.
For more than a decade I worked at Carnegie in an office next to the one used by Einstein during his summer visits to Pasadena and just above Edwin Hubble’s office. I was part of the team that developed the last, and most powerful instrument, to be deployed on the Hubble Space Telescope. This instrument has allowed us to see galaxies when the Universe was only 500 million years old! I am now working to support development of the next generation of giant telescopes on the ground, telescopes that Hubble could only dream of.
Today, I lead the team of scientists and engineers building the Giant Magellan Telescope (GMT), an enormous instrument comprised of seven primary mirror segments—the seven largest mirrors ever made—that will stretch to more than 80 feet across once complete. The GMT will explore the cosmos to observe the first stars in the universe, offering images 10 times sharper than those coming from the Hubble Space Telescope. Since 2008, I’ve served as the head of the non-profit corporation, GMTO, that is charged with carrying out the development, construction and operation of the telescope and related facilities. My day-to-day responsibilities include ensuring that the telescope and its instruments will be able to address the key questions at the forefront of astrophysics in 2020 and beyond.

Proof! 

I’ll be back at 1 pm EST (10 am PST, 6 pm UTC) to answer your questions, ask me anything!

Pretty sure i saw a meteor at about 00:30 last night. Are we passing through a comet tail?

Looking forward to the Perseids meteor shower - well the peak anyway as we're already within the period where we can see them. Have already spotted a few meteors when the night skies have been clear recently.

Ive seen a few over the last 3 nights with green trails, looks like a cloud-fest tonight so annoying:wallbash:, maybe friday night will be better...

Looks like  rosseta has landed on its final destination   looking forward to the pics being sent back.

Edit  here is one 5 or so miles from the comet

Should it be possible to see a star in broad daylight? Or more likely a planet? Possibly Venus is in the approximately SW sky right now?

 a belated reply, but yes, it is indeed Venus

saw that  earlier.  Possibly a new planet that orbits a seperate sun that could sustain life.?   Or Nibiru if you watch You Tube

I've seen a blog suggesting it will the announcement of additional planets around TRAPPIST-1 based on the blogger's looking into the the relevant scientists recent publications and correspondence.

https://en.wikipedia.org/wiki/TRAPPIST-1

Will have to wait and see if that is the case and if so, if there is any additional info along the lines of some of the UK press stories doing the rounds.

My view - I'm wondering if they've found Donald Trumps home planet?

      Managed to snap a quick pic of saturn with my celestron astromaster.

      The universe began with the big bang (Some may think others way of the beginning of the universe).
      But the universe has to end one day? Or will just go on forever? 
      There are some predictions about the fate of the universe.
       
      1.Big freeze
       
      This scenario is generally considered to be the most likely,as it occurs if the universe continues expanding as it has been. Over a time scale on the order of 1014 years or less, existing stars burn out, stars cease to be created, and the universe goes dark.Over a much longer time scale in the eras following this, the galaxy evaporates as the stellar remnants comprising it escape into space, and black holes evaporate via Hawking radiation.In some grand unified theories, proton decay after at least 1034 years will convert the remaining interstellar gas and stellar remnants into leptons (such as positrons and electrons) and photons. Some positrons and electrons will then recombine into photons.In this case, the universe has reached a high-entropy state consisting of a bath of particles and low-energy radiation. It is not known however whether it eventually achieves thermodynamic equilibrium.
       
      2.Big Crunch 
       
      If the energy density of dark energy were negative or the universe were closed, then it would be possible that the expansion of the universe would reverse and the universe would contract towards a hot, dense state. This is a required element of oscillatory universe scenarios, such as the cyclic model, although a Big Crunch does not necessarily imply an oscillatory Universe. Current observations suggest that this model of the universe is unlikely to be correct, and the expansion will continue or even accelerate.
       
      3.Big Rip
       
      This scenario is possible only if the energy density of dark energy actually increases without limit over time.[citation needed] Such dark energy is called phantom energy and is unlike any known kind of energy. In this case, the expansion rate of the universe will increase without limit. Gravitationally bound systems, such as clusters of galaxies, galaxies, and ultimately the Solar System will be torn apart. Eventually the expansion will be so rapid as to overcome the electromagnetic forces holding molecules and atoms together. Finally even atomic nuclei will be torn apart and the universe as we know it will end in an unusual kind of gravitational singularity. At the time of this singularity, the expansion rate of the universe will reach infinity, so that any and all forces (no matter how strong) that hold composite objects together (no matter how closely) will be overcome by this expansion, literally tearing everything apart.
       
      4.Vacuum metastability event
       
      If our universe is in a very long-lived false vacuum, it is possible that a small region of the universe will tunnel into a lower energy state. If this happens, all structures within will be destroyed instantaneously and the region will expand at near light speed, bringing destruction without any forewarning.
       
      5.Heat death
       
      The heat death is a possible final state of the universe, estimated at after 10150 years, in which it has "run down" to a state of no thermodynamic free energy to sustain motion or life. In physical terms, it has reached maximum entropy (because of this, the term "entropy" has often been confused with Heat Death, to the point of entropy being labelled as the "force killing the universe"). The hypothesis of a universal heat death stems from the 1850s ideas of William Thomson (Lord Kelvin) who extrapolated the theory of heat views of mechanical energy loss in nature, as embodied in the first two laws of thermodynamics, to universal operation.
       
      But its all a very long time away.
       
      So what do you think?
