This is a Simulation of the Interstellar Medium Flowing Like Smoke Throughout the Milky Way

How do stars form? We know they form from massive structures called molecular clouds, which themselves form from the Interstellar Medium (ISM). But how and why do certain types of stars form? Why, in some situations, does a star like our Sun form, versus a red dwarf or a blue giant? That’s one of the … Continue reading "This is a Simulation of the Interstellar Medium Flowing Like Smoke Throughout the Milky Way" The post This is a Simulation of the Interstellar Medium Flowing Like Smoke Throughout the Milky Way appeared first on Universe Today.

What Happens to Their Supermassive Black Holes When Galaxies Collide?

What’s better than two gigantic galaxies swirling into one another until they collide?  How about three galaxies swirling into one another until they collide – and they all have supermassive black holes at their core to boot!  Recently, a team led by Dr. Adi Foord of Stanford combed through data from the WISE mission and … Continue reading "What Happens to Their Supermassive Black Holes When Galaxies Collide?"

The Solar Wind is More Attracted to the Earth’s North Pole Than the South. Why?

Likely the most well-known result of the Earth’s magnetic field are the Aurora Borealis and Australis (Northern and Southern Lights).  When chargers particles from the solar wind run into the Earth’s magnetic field, they can occasionally elicit spectacular light displays.  For years now, scientists have thought that the charged particles that cause those displays were … Continue reading "The Solar Wind is More Attracted to the Earth’s North Pole Than the South.

The Ongoing Collapse of the World's Aquifers

When humans over-exploit underground water supplies, the ground collapses like a huge empty water bottles. It's called subsidence, and it could affect 1.6 billion people by 2040.

Almost a Third of Recovered COVID-19 Patients Return To Hospital In Five Months, One In Eight Die

According to new research from Leicester University and the Office for National Statistics (NS), almost a third of recovered COVID-19 patients will end up back in the hospital within five months and one in eight will die. Yahoo News reports via The Telegraph: Out of 47,780 people who were discharged from hospital in the first wave, 29.4 per cent were readmitted to hospital within 140 days, and 12.3 per cent of the total died. The current cut-off point for recording Covid deaths is 28 days after a positive test, so it may mean thousands more people should be included in the coronavirus death statistics. Researchers have called for urgent monitoring of people who have been discharged from hospital. Study author Kamlesh Khunti, professor of primary care diabetes and vascular medicine at Leicester University, said: "This is the largest study of people discharged from hospital after being admitted with Covid. People seem to be going home, getting long-term effects, coming back in and dying. We see nearly 30 per cent have been readmitted, and that's a lot of people. The numbers are so large. The message here is we really need to prepare for long Covid. It's a mammoth task to follow up with these patients and the NHS is really pushed at the moment, but some sort of monitoring needs to be arranged." The study found that Covid survivors were nearly three and a half times more likely to be readmitted to hospital, and die, in the 140 days timeframe than other hospital outpatients. Prof Khunti said the team had been surprised to find that many people were going back in with a new diagnosis, and many had developed heart, kidney and liver problems, as well as diabetes. "We don't know if it's because Covid destroyed the beta cells which make insulin and you get Type 1 diabetes, or whether it causes insulin resistance, and you develop Type 2, but we are seeing these surprising new diagnoses of diabetes,â he added. "We've seen studies where survivors have had MRS scans and they've cardiac problems and liver problems. These people urgently require follow up and the need to be on things like aspirin and statins."

The Magnetic Fields Swirling Within the Whirlpool Galaxy

Messier objects are some of the most imaged objects in the universe.  In part that’s because many of them are so visibly appealing.  A good example of that is the Whirlpool galaxy, M51, which recently received an even more dramatic visual representation with a new photo released by NASA.  In it, the magnetic fields that … Continue reading "The Magnetic Fields Swirling Within the Whirlpool Galaxy" The post The Magnetic Fields Swirling Within the Whirlpool Galaxy appeared first on Universe Today.

The First Cubesat With a Hall-Effect Thruster has Gone to Space

Student-led teams aren’t the only ones testing out novel electric propulsion techniques recently.  Back in November, a company called Exotrail successfully tested a completely new kind of electric propulsion system in space – a small hall-effect thruster. Hall effect thrusters themselves have been around for awhile.  However, they have been limited in their practicality, primarily … Continue reading "The First Cubesat With a Hall-Effect Thruster has Gone to Space" The post The First Cubesat With a Hall-Effect Thruster has Gone to Space appeared first on Universe Today.
