• Three more coronavirus symptoms were added to the official list that the Centers for Disease Control and Prevention (CDC) oversees.
  • Congestion or runny nose, nausea or vomiting, and diarrhea can be indicative of infection with the novel coronavirus, based on the update list of symptoms.
  • The symptoms aren’t enough for a definitive COVID-19 diagnosis, as they can appear in other medical conditions as well.

We’ve learned a lot about the novel coronavirus in a relatively short period of time. We know how it spreads, how long it can survive in the air and on surfaces, and how it kills. We also understand how it can be neutralized and what measures we need to take to reduce the risk of transmission.

But not everything is definitive. Authorities and doctors are learning as they go, and that’s why we end up getting more and more details about the disease every day. In this COVID-19 information deluge, we missed the three new symptoms that the CDC added to the official list to watch out for on its website.

If you’ve experienced congestion or runny nose, nausea or vomiting, or diarrhea recently, you might be infected. The three symptoms were added to the CDC’s coronavirus symptoms page on May 13th, according to Our Community Now. That’s the last time the page was updated, and those symptoms weren’t there before.

This is not the first time the CDC has updated the page, which it does every time it has new information to add. The last time the organization updated the list of COVID-19 symptoms was in late April when it added six symptoms to the list. The strangest COVID-19 symptom to date was one of the six: The loss of taste or smell.

Here’s the full list of symptoms to watch out for, according to the CDC:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

You don’t have to develop all these symptoms to have the disease. In fact, some people have no visible symptoms, but their bodies still fight off the infection.

The World Health Organization has a different way of listing coronavirus symptoms, dividing them into three categories:

Most common symptoms:

  • fever.
  • dry cough.
  • tiredness.

Less common symptoms:

  • aches and pains.
  • sore throat.
  • diarrhoea.
  • conjunctivitis.
  • headache.
  • loss of taste or smell.
  • a rash on skin, or discolouration of fingers or toes.

Serious symptoms:

  • difficulty breathing or shortness of breath.
  • chest pain or pressure.
  • loss of speech or movement.

If you suspect you’ve been exposed to COVID-19 and may have been infected, it’s best to seek medical guidance as soon as possible. The quicker the diagnosis is confirmed and the illness is treated, the better the outcome. Coronavirus symptoms may take time to develop, from 5 or 6 to 14 days, according to the WHO. The CDC says the onset of symptoms can start anywhere between 2 and 14 days after exposure.

  • A new video released by NASA crunches 10 years of Sun observations by the Solar Dynamics Observatory down into just over one hour.
  • The video shows the Sun moving between its maximum and minimum phases.
  • Solar storms can affect Earth, satellites, and even spacecraft, so keeping an eye on solar activity is a must.

The Sun is the star responsible for life on Earth. Without it, we wouldn’t be here, and it’s a constant fixture in our everyday lives. With all that in mind, it’s a real shame you’re not supposed to look directly at it. The Sun is an incredible thing, and astronomers have come up with ways to observe it without scorching their retinas. One of those tools is the Solar Dynamics Observatory, an “unblinking eye” that observes the Sun constantly.

Images from the SDO are produced by capturing only a specific ultraviolet wavelength that lets scientists see the star’s corona, which is its outermost layer. For a decade, the SDO has been staring at the Sun and recording every blip of activity it can spot. Now, we can enjoy it all for ourselves.

The timelapse video NASA just released is absolutely incredible. It shrinks ten years of Sun observations into just over one hour. Yep, it’s an hour-long video, so grab a cup of coffee and enjoy it.

The video, which is available in up to 4k resolution, is stunning. It shows a wealth of activity on the star’s surface early on, ramping up until there are magnetic loops of plasma covering a huge percentage of its surface. Then, just as quickly as they appear, the hot spots of activity seem to fade away, leaving the star looking much calmer.

This is the regular Sun cycle, where it moves from a period of high activity called the Solar Maximum to a period of low activity called the Solar Minimum. The intensity of the maximum and calmness of the minimum can vary, but the cycles themselves are very apparent.

As for why you occasionally see the Sun’s orb shake in the frame, or see momentary frames of darkness throughout the video, NASA has a very good explanation:

While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. The dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. A longer blackout in 2016 was caused by a temporary issue with the AIA instrument that was successfully resolved after a week. The images where the Sun is off-center were observed when SDO was calibrating its instruments.

Observing the Sun and keeping track of how active or inactive it is can be vital for predicting things like solar storms and other space weather that can affect Earth. When the Sun spews plasma into space, charged particles that reach Earth can damage communications satellites and even put space missions in peril.
