and you can test your knowledge and see some amazing experiments too
Checkout the Moon and Venus in east now.. You can see detail in the Moon’s ‘dark bit’ because it’s being gently illuminated by reflected sunlight from Earth. Venus is so bright because it is covered in cloud that reflects lots of light

The Spring Equinox is not a day but an exact moment in time. This year it takes place at 09:37 today and at that moment the Sun crosses the celestial equator in the sky heading north, summer is on its way
Great job
@GMB
naming the NHS staff who lost their lives during COVID19. MUCH respect for giving it time

Humbling that a mix of nationalities among them, maybe it’s time we start seeing ourselves as inhabitants of Earth rather than different countries
On arrival they cause the gas in atmosphere to glow like a neon tube. The different gasses give the different colours; green is low altitude oxygen, red is high altitude oxygen, other colours are nitrogen
This is my dad… he has dementia - played draughts with him last night and while we did not play the conventional rules and ended up just moving pieces randomly around the board, he smiled, first real smile I’ve seen in a long time. He’s still in there :(
Lots asking me what causes the northern lights and the different colour. The Sun kicks out electrically charged particles known as the solar wind which travels out at speeds in excess of 400 - 700km per second! 1/1
This is the latest version of my image of NGC7331, a galaxy which is so far away that the light that made this image left the galaxy when higher primates started to appear on Earth around 40million years ago!

If it’s clear where you are then join me outside from 10pm UK time and I’ll guide you where to look to see the
#Dragon
module as it flies over UK chasing the space station before docking
#FamilyStargazeWithMark
I love Christmas, I love my family, I want to see them at Christmas but who knows, I might be asymptomatic over Christmas so I will be
#StayingHomeForChristmas
because I don't want to give Covid-19 to my relatives as a Christmas present!
If you can get out of bed early tomorrow then look low in south east around 4 ish (below bright star Arcturus in Bootes) and you can see Jupiter and Mars very close together.. Plenty of clear skies forecast so no excuse, except sleep ;) Happy hunting and please RT
A large hole has appeared in the Sun's atmosphere (it’s normal), and is facing Earth. A stream of solar wind is expected to reach us in the late hours of Nov. 3rd. Quite likely an aurora on the cards this weekend - RT RT
@Astronomer_Mark
Nice to know the BBC realise the difference between astronomy and a load of old doggy do! Someone in the graphics dept needs a poke. 🤣
If anyone has started following me having seen me on
@BBCNews
today and is expecting astroLOGICAL tips. You should know my star-sign is a unicorn because they, like astrology DON’T EXIST! Go find Russell Grant ;)
Morning all. The
#WinterSolstice
is an exact moment in time, not a day! It occurs at 15:58 today when the Sun reaches its lowest point in the sky. After that point it slowly starts to climb higher again.
Unbelievable.. walked into a pub with a mask on and got asked why I had a mask on! Told the fella that there is still a pandemic, it’s still recommended, those working in pub wear a mask to protect me so I will wear one to protect them.. oh and it’s my personal choice
#Angry
Lots of you asking about seeing
@SpaceX
rocket. It goes over UK shortly but too bright at mo. It can be seen on its second pass over UK at 10:15pm. Lookout for Space Station at 10:11pm west to east and low in south, then rocket following on at 10:15pm
@georgie_grier
I’ve seen amazing shows with really poor audience numbers. Just because there was just one audience member doesn’t mean your show isn’t awesome. believe in yourself but maybe it’s the poster/marketing?
Well that’s my last nights sleep until fri 17 Sept.. 4 hours until I start my attempt to break Guinness world record for longest marathon lecture
#SpaceTalk2021
for all the up to date info follow
@GwrLecture
This evening two astronauts launch to the
#ISS
and we should be able to see their rocket catching up with the station later tonight.. stay tuned for more info later
Working on an image of NGC6820/NGC6823 (in Vulpecula). Sneak peek at a 10min sub in h-alpha. Lovely open cluster with reflection nebula at a distance of 6,000 light years.
Hey all.. thanks to everyone who has been following my rather long lecture. I’ve been humbled to see so much support and to see that we raised an incredible £11.5k for charity (and rising) LOADS of science to be got too.. had a 15 hr sleep and maybe a quick cheeky one again
Look due south right now and you can see a bright object near the Moon, the mighty planet Jupiter! They look close but are separated by 661.9 million km. It would take the International Space Station just over 1,000 days to travel that distance!
Ok so here’s the idea. Between 8:00 and 08:30 this eve I will be tweeting with the hashtag
#FamilyStargazeWithMark
and will guide you around some of the highlights of this evening sky. You won’t need a telescope, just your family, eyes and your phone/tablet.. please RT
Up to 20cm of snow they said, be prepared they said... wake up and as I feared it’s raining! Who else still has that childish disappointment when snow is forecast but doesn’t arrive ?
Have I read this correctly, Victoria (in Australia) has seen 13 cases of Covid so are going into lockdown meanwhile here in UK we had ~13,000 cases yesterday and there are calls to open up !? I do think perhaps Australia has the right approach
Oh I did manage to catch a Lyrid on my all sky camera last night. The radiant is the apparent position in the sky where Lyrid meteors seem to come from. The meteor is the streak in the sky below left of centre
#FamilyStargazeWithMark
Amazing that the first powered flight was in 1903 and now, just 118 years later have flown on another planet!!! Utterly amazing and well done to all involved
Who is up for trying to spot the
#Dragon
capsule as it flies over the UK in 15 mins!? Going to be tricky to see but it is doable. Head out now so we can be looking in right direction for the ISS first which appears at 10:11pm
#FamilyStargazeWithMark
In other news... There is a comet gracing our skies, Comet Atlas (C2019/Y4) is heading toward the Sun and assuming it doesn’t break up, it could brighten nicely. Certainly one to watch.
Hey
@reallorraine
I’m encouraging families to get outside at night in their back garden and let me guide them, via
@TwitterUK
to stargaze with me. Next session tonight from 8pm to 8.30pm
#FamilyStargazeWithMark
could you share please ?
Here’s the deal - tonight at 9.33pm UK time a
@SpaceX
rocket is launching two astronauts to the International Space Station. We should be able to see them pass over UK from west to east about half way between horizon and overhead 9.53pm -9.57pm
@Rylan
Awesome work… amazing to think the charged particles that caused that wee generated inside the sun maybe 400,000 yrs ago, then traveled toward Earth at 400 km/sec to make the gas in the atmosphere glow!
Heads up. It’s the weekend, it’s been hard for kids to adjust to lockdown and a lot of clear skies tonight so give them a treat, print off this voucher and let them stay up late for tonight’s
#FamilyStargazeWithMark
10.30pm-11pm Please RT
Well last night was unexpected. A few pics from South Norfolk taken with a phone! And to see this gentle glow in the atmosphere caused by charged particles from the Sun. Nature truly is remarkable, we really should stop messing up the planet
I do hope some of the
#FlatEarth
folk were watching the launch... I know it was a wide angle lens which distorted a little but still A SPHERICAL PLANET is a spherical planet.. Or rather oblate spheroid but that's just detail
This was without doubt the most AMAZING thing I have seen in space exploration for some time! Incredible to see them touch down at the same time and BANG on target..
#Amazing
Latest update on my wide field exploration of the Veil Nebula in Cygnus.. this image uses narrowband filters under almost full moon but shows nicely that narrowband is largely unaffected by moonlight. It is remains of star that exploded ~15,000 yrs ago, 2,400 light years away
Have I woken to see that Trump is losing so is trying to stop all remaining vote counts!? In any world that’s just being a sore loser! That’s the behaviour of a spoiled child not an (almost ex) world leader
Look to the east now (UK) and you can see two ‘stars’ very close together. The upper one is Venus and lower is Jupiter! They look close but in reality are separated by 711 million km!
@GMB
@BBCBreakfast
Can you see that really bright 'star' to the upper right of the Moon - less than one fist width away? That's no star, it's Jupiter, the largest planet in the Solar System

my local primary school had 27 kids out of 100 in the school test positive for COVID and it’s now hitting the parents !!!!!
