Until the 20th century, astronomers ignored the interiors of things. They had to. Telescopes only showed outermost layers.Scientists knew that a ball's "inside" constitutes virtually all its mass, but basic questions went unanswered: What, for example, lay below the dazzling solar surface? What mysteries might be found in the core of galaxies?

    Closest point to Earth
    Bob Berman
    If you're hearing this on Sunday, Saturn is at its closest point to Earth, and its rings appear as a straight white line due to their edge-on alignment — a rare event that occurs every 15 years during its equinox. Earth’s own equinox arrives Monday at 2:10 PM, marking the start of autumn in the Northern Hemisphere. This equinox often falls on the 22nd or 23rd because, as Kepler explained, Earth speeds up in its orbit when closer to the sun in January and slows down in July. That means winter is shorter than summer by about a week — a fact disguised by our calendar and the uneven placement of long and short months.

    A lunar standstill
    Bob Berman
    This year brings a rare lunar event called the Lunar Standstill, which happens only once every 18.5 years. Due to the Moon’s wobbling orbit aligning with Earth’s tilt, the Moon is reaching extreme positions in the sky. Recently, it appeared unusually low at first quarter, the third quarter Moon stood directly overhead—something typically impossible from the continental U.S. Even in daylight, the Moon remains high and visible, especially through sunglasses, offering a striking sight in the sky.

    Vega

    Vega, one of the brightest stars, is often mispronounced as "VAY-ga" but should be "WEE-ga," meaning "falling eagle" in Arabic. Visible at nightfall, it shines blue overhead, contrasting with the orange Arcturus. Located 25 light-years away, it’s 58 times brighter than the sun and spins much faster, completing a rotation in just 11 hours. In 12,000 years, Vega will become Earth's pole star. It also displays a rare blueshift, pointing to the direction we're traveling in space.
