Moon exploration has long been an exciting prospect, drawing the interest of various agencies and private companies alike – though their attempts often resulted in mixed outcomes. Surveyor 5 was equipped with a scoop designed to “weigh” lunar rocks, returning images that helped scientists map its surface composition. Mission controllers sent it crashing towards the…
After 21 hours on the Moon, Armstrong and Aldrin returned to their lunar module, known as Eagle. They disconnected it from the command module that would remain orbiting above, before undocking Eagle from Eagle itself and dismounting from it. Armstrong made history when he took “one small step for man, one giant leap for mankind”….
Mercury is an extremely dangerous toxic metal, known to harm children and babies’ brains, as well as cross the placenta to harm fetuses. Eating two servings of low-contaminant fish each week may reduce your exposure risk of mercury. Crab Grapsus grapsus from both urban and protected sites across Galapagos was collected for analysis to measure…
Anacondas are non-venomous constrictors that subdue prey by wrapping their muscular bodies tightly around it and squeezing until its asphyxiated, reports Wonderpolis.

The sky’s vibrant blue hue results from scattering of sunlight by Earth’s atmosphere, mostly composed of nitrogen and oxygen molecules smaller than wavelengths of light; they scatter blue light more effectively. Violet and red wavelengths tend to scatter less, thus leaving blue wavelengths for our eyes. Rayleigh Scattering Lord Rayleigh discovered in the 1800s that…
Mercury Retrograde occurs three to four times annually and can be extremely frustrating; however, it doesn’t have to be all bad! Named after the Roman messenger god Mercury, this planet of swift movement rules communication in all forms–listening, writing, reading and speaking–including negotiations and contracts as well as travel transportation and shipping activities. It happens…
NASA’s Parker Solar Probe has broken speed records over the last several years by continuously approaching closer and faster towards the Sun, picking up speed with each pass. But, what exactly is spacecraft speed, and how are scientists measuring it? In order to answer this question, let’s first determine what we mean by “speed.” To…
