Your Birthday Image. Thanks to the Hubble Telescope.
As of 2023, the Hubble Space Telescope continues its very important scientific work. Hubble has been operating in space for over 32 years, which is a lot longer than anyone expected.
The Hubble Telescope has provided us with well over a million fascinating images since it started its working life.
Look at the image above, it was taken on my birthday. It shows Jupiter and one of its moons, Ganymede.
If you would like to see an image Hubble took on your birthday, then please follow the link below.
Over its time in space, 5 manned service missions were sent to the Hubble Telescope. But sadly, no one will ever visit this famous telescope again.

Evolution, Or Not?

You are a highly advanced life form, but why has this happened? Why are you here?
Consider yourself extraordinary and unique, the odds against your existence are astronomical.
Evolutionary biologists agree that humans and all other living species are descended from simple bacteria-like ancestors.
Bacteria can be traced back at least 3.5 billion years. Over countless generations, small modifications have taken place, and the small changes that are more favourable to life are more likely to be passed on to the next generation. This has been happening since the first life appeared on our planet.
In most cases evolution is a very slow process, the small changes taking place are called natural selection. This is the reason you are here and reading this article today.
Life is amazing, but it must be said that it is not yet fully understood why life got a start, but we know how it has evolved.
I know many people will have their own thoughts about why we are here but everyone is entitled to their opinions or beliefs.

The Reason For A Leap Year.

Earth takes 24 hours to make one complete rotation on its axis. We know that time as a day.
We are all aware that there are 365 days in our calendar year, but a solar year is actually 365 days, 5 hours, 48 minutes and 46 seconds, the exact time the Earth takes to make a complete circuit or orbit around the Sun.
That is the reason a time adjustment is needed, and a leap day is added to the end of February every 4 years. You will know it as a leap year.
That additional leap day is added to keep the calendar year synchronised with a solar year.

The Cosmic Dark Ages.

The Universe is thought to have come into existence about 13.8 billion years ago, but there were no stars at that time. Look at the image above and imagine what space would have looked like.
Most of us are familiar with the night sky. We look up and see the Moon. We can also see some of the planets and of course, we can view the stars, but we can only see the Moon and planets because of reflected light coming from the Sun.
But space has not always been like that. It took about 200 million years after the big bang (the birth of the Universe) for stars to form and shine.
Surprisingly, we can also see the Andromeda galaxy with unaided eyes. The Andromeda galaxy is over 2.5 million light-years away.
Imagine, for every hour of that 2.5 million years, the light from that galaxy has travelled 1,080 million kilometres towards us.
Yes, it is mind-boggling.

I hope you find some of my articles interesting.
Our highly developed brain has given us intelligence and curiosity, now with the help of sophisticated scientific instruments, we can try and make sense of the Universe and our existence.
This was delighting to go through, i am checking out the nasa page now for the image generated at 09091996 :P
Author. My articles are written for people with an average understanding of the universe and life. We are not all experts. I hope you gain some knowledge if you decide to read them. Regards.
