全食日与彗星
影像提供与版权: Lin Zixuan(林子轩)(Tsinghua U.)

说明: 上星期的日全食期间,太阳附近出现了不只1颗彗星。预期会出现的彗星是庞士-布鲁克斯彗星( 12P/Pons-Brooks),但它让许多人失望了,因为亮度远不如预期。不过,在长曝光相机影像里,倒是相对不知名的SOHO-5008彗星也现身其中。这颗彗星是从欧洲航天局和美国航太总署的太阳轨道SOHO卫星所拍摄的影像里,辨识出的第5008颗彗星。可能极为娇小的SOHO-5008彗星,是一颗掠日彗星,在近距离掠过太阳后的数个小时之内就崩解了。这张主题影像不仅因在日全食期间记录到2颗彗星而显得不寻常,更因为是极罕见的从地面拍到掠日彗星。影像中还可以看到太阳广袤的日冕、水星(左)和金星(右)。在4月8日扫过北美洲的黝黑月影下方,这幅影像所呈现的行星和彗星之中,只有金星轻易可为聚集在北美各地的数百万观察者所见。

However, analysts are positive on the stock now. “We have seen a huge downside movement in the stock due to the central electricity regulatory commission’s (CERC) order that seems to be negative from 2014-15 onwards but we cannot take a linear negative view on the stock and further downside movement on the stock is unlikely. Currently stock is underpriced. Investors can bet on it for a longer horizon," said Vivek Gupta, director research at CapitalVia Global Research.

How to Buy Bitcoin?

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
