Astronomy
- by Elisa NeckarIn 1976, the Soviet Union began development of the Buran orbiter. Concerned that the American space shuttle program might be used for military purposes, the Soviets responded with Buran and its Energia booster rocket, which were capable of carrying antisatellite and antimissile weapons and targeting locations on Earth’s surface. Though the nonmilitary objectives for BuranContinue […]

- by Michael E. BakichFor decades, amateur astronomers have railed against light pollution — the single greatest negative impact of humans on the night sky. Initially, the argument was, “We can’t see the stars anymore!” More studies revealed how Artificial Light At Night (ALAN) is detrimental to sleep patterns and causes fatigue and stress in both humans and animals. Could thingsContinue […]
- by Jake ParksThe phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moon’s orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back toContinue […]
- by Elisa NeckarThe Kepler Space Telescope, launched March 6, 2009, was designed to search the Milky Way for exoplanets. Using the transit method, Kepler ultimately observed over 500,00 stars and contributed to the discovery of almost 2,700 exoplanets. Though Kepler was originally intended for a 3.5-year mission, NASA announced on Nov. 14, 2012, that the space telescopeContinue […]

Universe Today
- The Shenzhou-20 mission's three-person crew has returned home after more than a week of delays caused by damage to their spacecraft, allegedly caused by an impact with a tiny piece of space debris.
- Astronomers have discovered that the famous Pleiades star cluster, otherwise known as the "Seven Sisters" is actually the bright core of a sprawling family of stars spread across nearly 2,000 light years. By combining stellar spin measurements with precise motion tracking, researchers identified over 3,000 related stars and revealed the Pleiades is twenty times larger […]
- Astronomers have discovered that our Solar System is moving through the universe more than three times faster than cosmological models predict, a finding that challenges fundamental assumptions about how the universe works. By analysing the distribution of distant radio galaxies using advanced statistical methods, the team detected motion so unexpectedly rapid it earned the rare […]
- Carl Sagan, along with co-author Edwin Salpeter, famously published a paper in the 70s about the possibility of finding life in the cloud of Jupiter. They specifically described “sinkers, floaters, and hunters” that could live floating and moving in the atmosphere of our solar system’s largest planet. He also famously talked about how clouds on […]
- The next few months are likely to bring a dramatic transition for NASA, under the leadership of a new administrator who has new ideas about changing the course of the space agency.
- The JWST surprised when it detected very early galaxies that were extremely luminous. This suggested that they were more massive than researchers thought they could be. Not enough time had passed for them to grow so large. New research has an explanation.

- Video: 00:00:22 The Sun is always mesmerising to watch, but Solar Orbiter captured a special treat on camera: a dark ‘prominence’ sticking out from the side of the Sun. The dark-looking material is dense plasma (charged gas) trapped by the Sun's complex magnetic field. It looks dark because it is cooler than its surroundings, being around 10 000 °C compared to the surrounding million-degree plasma. When viewed against the background of […]
