More than a million satellites could make the night sky three times brighter

A new model has examined how light reflected from satellites and mirrors in space affects astronomical cameras and the brightness of the night sky. The results show that even dim satellites can erase parts of wide-field sky images,

Israeli study: Street lighting causes thousands of mosses to move in circles

Researchers from the Hebrew University of Jerusalem have documented for the first time the coordinated circular movement of thousands of terrestrial isopods of the species Armadillo sordidus. According to the study, the phenomenon is caused by artificial lighting at night, and not by breeding or magnetic attraction.

Artificial night light disrupts the immune system of wild rodents

A study from Tel Aviv University found that artificial lighting at night, even at the intensity of street lighting, disrupts the activity patterns of the immune system in wild rodents and may increase the risk of mortality.

Light pollution disrupts crickets' circadian rhythms and threatens their reproduction

Further research on crickets reveals that light pollution throws them out of sync, impairs their reproductive ability, and threatens their continued existence.

Dunes in Danger: Who Will Save the Sand Between the City and the Sea?

Open sandy areas on the coastal plain are shrinking at an alarming rate, and invasive vegetation is changing the landscape. The State of Nature report calls for stopping the change before it's too late

The light that extinguishes the crickets' song

When the night is no longer dark, crickets' sexual communication is compromised. Studies in Israel reveal the ecological toll that night lighting takes on crickets and explain how we can help them

When light disturbs nature: Light pollution threatens green sea turtles | Angle

Although light symbolizes progress, for green sea turtles it is the opposite of a miracle. Mapping the lighting on beaches shows that not all darkness needs to be banished.

A new study reveals: the proliferation of satellites and space debris around the Earth is harming space exploration

A new study published in the journal Nature Astronomy. According to the study, the fact that satellites have become smaller and cheaper allows more and more commercial companies and government agencies to send satellites into space, a situation that has led to growth

The rate of land and sea warming in Israel is faster than the world average - from the State of Nature 2022 report trends and threats

The 2022 State of Nature Report, Volume Trends and Threats, presents a snapshot of key factors and processes that affect the state of nature in Israel as a result of human activity. The Fabric is the national program for assessing the state of nature in

We came to bring back darkness

Why was it easier for Galileo Galilei to observe the starry night sky than for us? Since in his time the light bulb had not yet been invented! It turns out that light pollution caused by artificial lighting is not only disturbing
