Mining Ethereum does not require large amounts of processing power as is the case with Bitcoin. Pixabay

Buying Ethereum may have been on your mind for some time now given how good of an investment it is proving to become.

So here’s a quick no-nonsense guide on how you become the owner of some Ethereum fast and easy:

  • Get an Ethereum wallet: Don’t be that person who goes shopping for Ethereum without having a secure wallet to store the coins in. Ledger and Trezor are highly recommended when it comes to hardware wallets and there are some decent software wallets that you can take a look at as well. Hardware wallets are generally considered safer because they are harder to hack and your information is not stored online.
  • Buy Ethereum with Credit Card: This is the easiest way to buy Ethereum. You can use CoinSwitch for this. Setting up an account takes very little time compared to the rigorous verification most other exchanges ask you to go through. CoinSwitch is the world’s largest aggregator of cryptocurrency exchanges and has minimal withdrawal and transaction fees making it the best exchange for you to purchase Ethereum with your credit card. In fact, you can even use a pre-paid credit card to avoid divulging any personal information.
  • Buy Ethereum with Bitcoin: This method is more a trade than a purchase but you can easily do this. Again, the best place to do this is CoinSwitch because it has the best exchange rates possible. Simply connect your wallet to CoinSwitch and make the purchase within minutes (provided the transaction isn’t large). CoinSwitch allows you to trade between 45,000 pairs and supports over 300 crypto coins. However, make sure to double-check on the daily and monthly limit if you plan on doing this regularly.
  • Ether ATM: You can always use a local Ether ATM machine much like you do for fiat currencies to buy Ether. This is not the fastest way as you actually have to locate one but when Ether ATMs are more widespread, it could be a viable way.
  • Bank Transfer: You can always fiat currency to buy Ethereum. Make sure you are aware of the exchange rate before you start the transaction.

  • Use the mobile wallet app: Some apps have integrated exchanges within the app itself. This is a very convenient way to convert your holdings to Ethereum or purchase Ethereum directly.
  • Peer-to-peer marketplace: Local Etherum allows you to find peers within your locality who are willing to sell Ethereum for cash, bank transfer, PayPal, or other peer-to-peer cash apps. The key is to not conduct large transactions through the site and always read seller reviews. The site has an escrow account which prevents scammers from duping you.
  • Send the money to your wallet: This is the last step but the most crucial one of all. You just need your Ethereum address to send the money from the exchange to your wallet.

Apart from these methods, you can always mine Ethereum. Mining Ethereum does not require large amounts of processing power as is the case with Bitcoin. However, when it moves to the PoS algorithm instead of the PoW that it uses now, mining may not be as lucrative. How much you can make from mining depends on

  1. Hash Rates
  2. Mining power
  3. Electrical cost

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal

Indian astronomers have found an active galaxy in a very bright state with 10 times more X-ray emission than normal, equivalent to more than 10 trillion of the sun, and located five billion light years away that could help probe how particles behave under intense gravity and acceleration to the speed of light.

It could help study the role of strong gravity and acceleration of matter in the formation, interaction and evolution of galaxies in the early universe.

Every galaxy in the universe is believed to host a supermassive black hole at its centre. In some galaxies, the black hole is actively devouring a large amount of material and shooting a jet of plasma almost at the speed of light towards us. These are called blazars.

OJ 287 belongs to a class of blazars known as BL Lacertae objects which show very rapid and large amplitude flux variations but barely discernible emission line features.

This class of sources emit in the whole electromagnetic spectrum, a rather uncommon phenomenon which requires extreme physical conditions. Hence, a study of such sources tells us about the behaviour of matter in an extreme gravitational field where it is difficult for light to escape from the vicinity of the black hole.

Astronomers at Aryabhatta Research Institute of Observational Sciences, an autonomous institute of the Department of Science and Technology, Government of India, have been monitoring one such black hole system named 'OJ 287' since 2015. This source shows a repeated optical brightness enhancement almost every 12 years.

"The repeated optical enhancement makes OJ 287 very intriguing as this class of sources does not show any repeating features in flux variations. The repeated optical enhancement made the researchers believe that the system hosts a binary black hole," said a release from the Ministry of Science and Technology.

In 2020, the source was very bright at optical and X-ray bands with X-ray flux more than 10 times the normal (non-active phase) flux. This flare was very different as it was not expected in models proposed for this source and thus, indicated a more complex system and physical conditions.

Investigating the extreme brightness shown by OJ 287 at optical and X-ray bands, astronomers led by Pankaj Kushwaha and Alok C. Gupta reported the source in a completely new spectral state.

The team argued that this change of state holds clues to the researcher's quest to understand how matter behaves in very strong gravity and how it accelerates the particle to almost the speed of light -- a feat that is out of the scope of even the most advanced CERN accelerator.

The research published in 'The Astrophysical Journal' tracked the details of changes in optical to the X-ray emission spectrum of the source with time from 2017 to 2020 -- after the second brightest X-ray flare of the source. It revealed how the source gradually started to change its spectral behaviour from mid-2018 to the new spectral state in 2020.

The study included data recorded by the ground-based facility operated by Physical Research Laboratory, Ahmedabad, operated Mount Abu observing facility in near infra-red bands and the space-based NASA's satellites -- the Niels Gherel Swift satellite at optical, UV and X-rays with gamma ray data from the Fermi satellite, the release added.

Tospread awareness about the significance of reading, Rachna Kalra, who hails from Gurugram (Haryana), started the Silent Book Club in the year 2019.

Who doesn't like reading, and that, too, reading along the company of mother nature? Well, this book club is truly a fantasy turned to reality.

As said by a regular reader at the Silent Book Club, “There is something meditative about reading. Sitting quietly with a book, without any distractions, is almost spiritual for me," this exactly is the case with many such readers.
