The researchers have unravelled that the blue Earth - which in today's times has green terrains and blue oceans - was once a huge chunk of ice.&nbsp;

The scenario of "Snowball Earth" is not some sort of imagination but the reality of Earth millions of years ago.

In a new study conducted by the researchers of the University of Colorado Boulder, evidence has been found which indicated that the Earth was covered by giant glaciers till the equator millions of years ago.&nbsp;

Because of the nature of the planet, Earth appeared like a celestial icicle.&nbsp;

<h2>What led to the Snowball Earth?</h2>

The study has added more evidence to the theory of Snowball Earth according to which from around 720 to 635 million years ago the climate of the planet was altered radically by various events.&nbsp;

The temperatures dropped and huge ice sheets enveloped the planet from pole to pole.&nbsp;

“This study presents the first physical evidence that Snowball Earth reached the heart of continents at the equator,” stated Liam Courtney-Davies, who is a postdoctoral researcher in the Department of Geological Sciences at&nbsp;CU Boulder and lead author of the new study.&nbsp;

<h2>How the study was carried out?</h2>

The focus of the research was centred on the Front Range of Colorado’s Rocky Mountains which held the coveted key to the frigid past, according to Courtney-Davies.&nbsp;

A dating technique, called laser ablation mass spectrometry, was utilised by the geologists.&nbsp;

In this process, the scientists found that the rocks were forced underground between 690 to 660 million years ago because of the weight of the overlying glaciers.

<h2>Did life exist on Snowball Earth?</h2>

Courtney-Davies said that theory suggests the appearance of the first multicellular organisms in oceans after Snowball Earth thawed out.

“You have the climate evolving, and you have life evolving with it. All of these things happened during Snowball Earth upheaval,” said Courtney-Davies.&nbsp;

“We have to better characterize this entire time period to understand how we and the planet evolved together. We want to get the word out so that others try and find these features and help us build a more complete picture of Snowball Earth,” he added.&nbsp;

Was Blue Earth once a 'snowball'? Here's the truth of the bluish-green planet

The most beautiful thermal pool of Yellowstone - Morning Glory - has gone through a drastic colour change from pristine blue to multi-hued colours, and the tourists are being blamed for this.

As per the officials, the reason behind this colour change is the accumulation of coins and trash in the pool, The New York Post reported.

The Morning Glory Pool, which is near the famous “Old Faithful” geyser, is a famous tourist attraction in Yellowstone National Park's Upper Geyser Basin.

“There are some lovely quotes about its beauty and stunning blue colours, and likening it to the Morning Glory flower,” said Yellowstone National Park historian Alicia Murphy, while speaking to The New York Post.

However, the early visitors were not worried about the environment and did not practice the stringent “leave no trace” policy, as instructed by the park officials.

<h2>Pool turns into a wishing well</h2>

The tourists were treating the blue pool as a wishing well and throwing coins, handkerchiefs, and other things inside.

“People didn’t understand the plumbing and how geysers worked. There were lots of ideas about, ‘If we throw something into this pool, we might be able to make it erupt'," Murphy said.

These items deteriorated the natural beauty of the pool and turned its deep-blue water into a mix of greens, yellows, blues, and oranges.

“I think there was some trial and error and a misunderstanding of the damage they were doing,” she said.

“Wishing wells are a time-honoured tradition. Flip a coin into a wishing well and make a wish. There is something about a pool of water that gives humans a weird instinct to throw things into it," she added.

Scientist-in-charge of the Yellowstone Volcano Observatory, Mike Poland, said that the changing temperature of the thermal pool is a major reason for its change in colour.

“Temperature is a huge factor. Hotter pools tend to be a brilliant blue, and cooler pools can be more colourful since bacteria can grow there," he said.

“At Morning Glory, the temperature cooled because people throwing objects in caused the conduit to become partially blocked, and the temperature went down, allowing different types of bacteria to grow," Poland said.

<h2>How the pools were cleaned earlier?</h2>

Former Yellowstone ranger Jeff Henry said the pools of the National Park Service at one time went through regular cleanups.

“A guy was hooked up to a climbing harness so that he wouldn’t fall into the pool, and he was out there with a long-handled net, fishing things out of the water far down into the crater of the pool," Henry said.

In this process, hundreds of items were fished out from the pool.

“We found tons, probably thousands of coins. There were a lot of rocks that didn’t belong there, and I think we found some hats that probably had blown off people’s heads and landed in the pool. And they, wisely, didn’t try to retrieve them," Henry said.

“Cleaning of pools was done on a regular basis. But values change, and they don’t clean the pools anymore, at least with the frequency and at the scale that we did," he said.

Yellowstone's thermal pool ‘Morning Glory’ has turned multi-hued from pristine blue. Here's why

Ever since Elon Musk-owned twitter began its blue tick purge on Thursday, multiple people have lost their twitter verification tags. Among those are many Indian celebrities and politicians. Among the politicians who lost verified account status. Are west Bengal chief minister Mamata Banerjee, opposition leader Rahul Gandhi, Delhi chief minister Arvind Kejriwal. Coming to actors, superstars like Priyanka Chopra Jonas, Shah Rukh Khan, Salman Khan, Deepika Padukone and Ram Charan...The actor in the film RRR. All of them have lost the blue tick on their twitter handles. If we talks of the sportspersons... Cricketer Virat Kohli, Olympic gold medalist Neeraj Chopra, former world champion boxer mc Nary Kom. Are among the high-profile names to lose the twitter-verified badges. It needs to be noted that these names are not only known in India but around the world. Each of these accounts have millions of followers. Many say that having a blue tick under the new system is no longer credible as now anyone can get it by a paying a monthly subscription.
