Following a series of successful maneuvers, India’s Chandrayaan-2 spacecraft has shifted trajectories and is now on its way to the moon.
A USGS study identified plastic in more than 90% of rainwater samples taken from across Colorado.

Research at one of the world’s clearest, cleanest lakes suggests the problem of microplastics is widespread in freshwater systems and not just in oceans.

When Israel’s Beresheet lunar spacecraft crashed in April 2019, there were thousands of microscopic, dehydrated tardigrades – water bears – aboard.
This is a tardigrade, also known as a water bear. A few thousand of them (dehydrated) were sent to the moon on the Beresheet spacecraft, which crashed on April 22, 2019. Aren't they cute? Image via Eye of Science/Science Source/ScienceNews.
Lists of common full moon names – both by month and by season – for North America.
Hubble image of an interacting galactic duo known as UGC 2369.
The pair of strange, luminescent creatures at play in this image are actually galaxies — realms of millions upon millions of stars. This galactic duo is known as UGC 2369. The galaxies are interacting, meaning that their mutual gravitational attraction is pulling them closer and closer together and distorting their shapes in the process. A tenuous bridge of gas, dust, and stars can be seen connecting the two galaxies,, during which they pulled material out into space across the diminishing divide between them. Interaction with others is a common event in the history of most galaxies. For larger galaxies like the Milky Way, the majority of these interactions involve significantly smaller so-called dwarf galaxies. But every few aeons, a more momentous event can occur. For our home galaxy, the next big event will take place in about four billion years, when it will collide with its bigger neighbour, the Andromeda Galaxy. Over time, the two galaxies will likely merge into one — already nicknamed Milkomeda.
Tomorrow, the spacecraft will shift from its orbit of Earth toward a path to the moon.
At Palomar Observatory near San Diego, a dedicated telescope spends its nights surveying the heavens. A recent analysis of its data revealed 4 stars that change in brightness, over just minutes.

It’s nearly full moon. So you might see an extra-large-looking moon low in the sky, one evening soon. Why does the moon look so big? It’s because of the “moon illusion,” a trick your brain is playing.
