Solar Eclipse 2024 coming! 8th April. I wish to see this with my own eyes on a location. Well, projection screen.

Book a flight and get you one of those energy and crystal gals… trust me, you’ll get more than a nice view

Usually cloudy with cold rain that time of year in the northern hemisphere. Spring time weather….April showers bring May flowers. So don’t get hopes of actually seeing complete eclipse

This is interesting when put like this

And more will be out of our reach if people keep bringing cutlass over land, since they're all moving away from us in shame. (Unless someone figures out the exotic materials needed for the Alcubierre drive to work, then we can go anywhere).

Rare green comet Nishimura visible tonight



After 435 years, a rare bright green comet is making its way towards the Sun.

The last sighting of this comet took place at least two decades before Italian scientist Galileo Galilei designed a telescope in 1609.

Nishimura, named after the amateur Japanese astronomer Hideo Nishimura, who also discovered two other comets, is expected to be visible from the northern hemisphere.

The comet is due to be closest to Earth on September 12.

According to The Sky Live website, Nishimura should be visible from Trinidad and Tobago, with the use of binoculars, at 5.19 am tomorrow, before sunrise, near the constellation Leo.

As long as this comet survives its travel towards the Sun, it won’t return to Earth again for another 430 years – around the year 2458.

The Sky Live also says some planets will be visible to the naked eye tonight:

Mars at 7.15 pm

Saturn, which rises at 5.12 pm and sets at 4.55 am

Jupiter, which rises at 9:27 pm and sets at 9:48 am

Venus at 3.31 am

Mercury at 5.19 am

who waking up to see it?

[DMan7]

You go get a nice dose of heavy cloud cover.

[st7]

anyone saw it?

[sMASH]

I forgot... And woke up in vastly sufficient time

[maj. tom]

I only got to see Uranus

View of the meteor that has been spotted across Trinidad and Tobago, Grenada, St. Vincent and Barbados at 7:19 PM Tuesday, September 12th, 2023.

[Duane 3NE 2NR]

^ wow missed that

[Dave]

Damn so I thought it was fireworks

[st7]

lol look how bright it light up! that would have been something to witness

[Duane 3NE 2NR]

got it on a security camera at home - 7:19pm and 35sec

[j.o.e]

That was crazy bright ….. was in porch and jumped when I saw the flash out of the corner of my eye. Left a long streak of sparks in the sky

[Duane 3NE 2NR]

seeing ppl on social media thinking this is the comet.
This isn't the comet. It's a meteor.

[st7]

it was a starlink satellite

[aaron17]

Bro .. I saw something landed in my back yard...and some kinda humanoid figures came out of an orb. They had big black eyes and long arms and legs..They seem they were staring into my soul. Anyways , I grabbed my camera phone and took some video but it came out like smudged up pixels.

Report on the meteor from the Guardian Newspaper today

A spectacular sight streaked across the night skies on Tues- day, just after 7.19 pm, as a me- teor burnt up in the atmosphere. The meteor was seen as far south as Venezuela, across Trinidad and Tobago, and as far north as Antigua and Barbuda.
According to GOES-16 Geosta- tionary Lightning Data, which can detect the brightness of the burning meteor in the atmos- phere as lightning based on its sensors, the meteor burnt di- rectly over northern Grenada.
As it burnt in the atmosphere, the meteor created a green or teal glow and left a bright orange trail. The colours of the glow and trail indicate the dominant
chemical composition of mete- ors, with green suggesting a high magnesium content. In contrast, an orange trail shows a high so- dium content.
What a meteor is made out of is one of many factors that deter- mine the colour that it appears. The speed at which the meteor enters the Earth’s atmosphere can also affect its colour. The faster a meteor moves, the more intense the colour may appear, according to the American Me- teorological Society (AMS). The AMS also added that slow mete- ors were red or orange among fainter objects, while fast mete- ors frequently had a blue colour.
Meteors generally begin to burn as they hit the Earth’s at- mosphere, resulting in bright light emanating between 65 and 120 kilometres above the Earth’s
surface. Meteors also dive into the atmosphere at speeds rang- ing from 40,200 to 257,500 kilo- metres per hour.
While there were no reports of any “space rocks” hitting the ground in Grenada on Tuesday night, which would then be called meteorites, meteors frequently burn up worldwide, including in the Caribbean region. Colloqui- ally called shooting stars, these meteor re-entries peak during meteor showers where the Earth passes through debris from com- ets, leading to these pieces of space rock or dust burning in the Earth’s atmosphere.
The Taurid Meteor shower is underway. It began on Septem- ber 10 and will run until Novem- ber 20.
It is predicted to peak on No- vember 13.

A sample taken from the Bennu asteroid is set to return to earth on September 24th 2023

NASA's OSIRIS-REx asteroid sample return mission faces the most difficult part of its journey as it approaches Earth for atmospheric reentry and recovery. The spacecraft is on course to deliver a capsule that will touch down in a western United States desert Sept. 24, completing a seven-year journey and making it the first NASA mission to retrieve surface material from an asteroid.

Osiris has landed in Utah carrying the sample from the Bennu asteroid!

If the Universe is 13.7 BILLION years old - How can you see an Einstein Ring 21 BILLION light-years away?

'Einstein ring' snapped by James Webb Space Telescope is most distant gravitationally lensed object ever seen
By Harry Baker published 3 days ago

The James Webb Space Telescope has taken a stunning image of a perfectly formed Einstein ring, which is also the most distant gravitationally lensed object ever detected.

Photos snapped by the James Webb Space Telescope (JWST) have revealed the farthest-ever example of an "Einstein ring." The record-breaking halo of warped light, which is a whopping 21 billion light-years away, is unusually perfect and surrounds a mysteriously dense galaxy.

An Einstein ring is an extremely rare type of gravitationally lensed object that was first predicted by Albert Einstein's theory of relativity. Gravitational lensing occurs when the immense gravity of a massive foreground object, such as a galaxy cluster or a black hole, warps space-time around itself; light emitted by more distant objects, such as galaxies or supernovas, that passes through this warped space-time also appears curved and warped from our perspective on Earth.

Got it. Thanks.

We can see a radius of about 46 billion light years. The universe has been expanding at an incredible rate since the Big Bang and is still expanding; see Hubble's Law and Dark Energy.

So we can see further than the universe is old.

[maj. tom]

No. Things are not where they used to be in space at a particular time in the past because the universe is expanding everywhere all the time. Light has a finite speed but space is also expanding. So if light started from a source about 13 Gya it has stretched through space-time to be now at what is now 46 Glya. In addition to the cosmic inflation right after the Big Bang.

And I can't tell if you really are interested and want more info or trying one of your forum science buster stints.

LOLZ. So light from the so-called Big Bang continues moving outward to this day.

Why is light-travel constrained by 186,282 mps? I know about the constant and mass doubling as you travel closer to the speed of light and all that stuff. One day, this figure will change.

It is incredible to think that some of the stars we see today no longer exist and we will not know this for millions of years.

Even NASA uses the term "chicken curry". Oh, the humanity!

Eating, meanwhile, is under discussion at JSC's Space Food Systems Laboratory. The crew is testing out foods that will be safe to carry into orbit, as well as suitable for their individual needs and tastes. The laboratory has hundreds of options available, including such dishes as cashew chicken curry, shrimp cocktail and chocolate pudding cake, according to a recent JSC Instagram post.
