Over 5 million users signed up for Threads in the first four hours of its launch, per Meta CEO Mark Zuckerberg. Meta CEO Mark Zuckerberg ratcheted his rivalry with Twitter owner Elon Musk as Meta rolled out its Threads app to users in 100 countries on Wednesday. Over five million users signed up for the app in the first four hours of its launch, Zuckerberg posted on Threads. The app somewhat resembles Twitter, leading Zuckerberg to post his first tweet in a decade — the famed Spider-Man pointing at Spider-Man meme. To be sure, Meta's Threads isn't the only game in town trying to the Twitter Killer.

Meta launched Threads social media platform — its answer to Twitter — on Wednesday. 10 million users signed up for Threads in the first seven hours of its launch, per CEO Mark Zuckerberg. Analysts say it could be tough for Threads to outshine Twitter's existing power user base. And even though Threads launching at an advantageous time, at least four Wall Street analysts say it could be challenging to outshine the incumbent. After all, it could be difficult to get Twitter users to move, Billy Duberstein, a portfolio manager at Stone Oak Capital, wrote on the Motley Fool website on Wednesday.

Solar maximum is a peak in the sun's activity that happens around the middle of each solar cycle. Mathew OwensThe solar maximum represents a peak in solar activity when the sun's magnetic field reaches its strongest and most disordered and dynamic point. NASA/Solar Dynamics ObservatorySolar cycles typically last 11 years, and the solar maximum happens roughly in the middle of each cycle. The sun's magnetic field reaches peak strength during solar maximum, generating an increase in events like solar flares and coronal mass ejections. These bursts are around four times as likely to occur during a solar maximum than a solar minimum.
Two huge coronal holes, dozen of times the size of the Earth, have appeared on the sun. These coronal holes can spew solar winds at 1.8 million mph toward our planet, which can cause stunning auroras and disrupt satellites. Coronal holes aren't actually holes in the sunA coronal hole rotates across the face of the sun, streaming solar wind towards Earth, February 1, 2017. Coronal holes happen in the "corona," the atmosphere of the sun, and can only be seen in UV or X-ray light. We could see this month's coronal holes again next monthThe coronal hole came into view as the sun rotated.
