Black Holes
Description
Discover the secrets of the most mysterious celestial bodies in the universe, whose gravitational pull is so immense that nothing can escape them—not even light. This guide explains how black holes are formed from the collapse of massive stars, what defines the "event horizon," and why, despite being invisible, they can be detected through their profound influence on their immediate surroundings.

חורים שחורים (2010-05-03)
גלו את הסודות של גרמי השמיים המסתוריים ביותר ביקום, שכוח הכבידה שלהם כה חזק עד שדבר לא יכול לחמוק מהם, אפילו לא אור. המדריך מסביר כיצד נוצרים חורים שחורים מקריסת כוכבים מאסיביים, מהו "אופק האירועים" ומדוע למרות שהם בלתי נראים, ניתן לזהות אותם באמצעות השפעתם על סביבתם הקרובה.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
