Venus : the planet second in order from the sun — Webster

OneLook, Free Dictionary, Wiktionary, Urban Dictionary

Encyclopedia

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. The planet is named after Venus, the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°. Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, for which reason it has been known as the Morning Star or Evening Star. Venus is classified as a terrestrial planet and it is sometimes called Earth’s “sister planet” due to the similar size, gravity, and bulk composition. — Wikipedia

  • Is there life adrift in the clouds of Venus?
    on March 30, 2018 at 9:13 pm

    In the search for extraterrestrial life, scientists have turned over all sorts of rocks. Mars, for example, has geological features that suggest it once had -- and still has -- subsurface liquid water. Scientists have also eyed Saturn's moons as well as Jupiter's as possible havens for life in the oceans under their icy crusts. Now, however, scientists are dusting off an old idea that promises a new vista in the hunt for life beyond Earth: the clouds of Venus. […]

  • Equatorial jet in Venusian atmosphere
    on September 1, 2017 at 1:38 pm

    Observations by Japan's Venus climate orbiter Akatsuki have revealed an equatorial jet in the lower to middle cloud layer of the planet's atmosphere, a finding that could be pivotal to unraveling a phenomenon called superrotation. […]

  • Venus's turbulent atmosphere
    on July 25, 2017 at 4:20 pm

    Astronomers shed light on the so far unexplored nightside circulation at the upper cloud level of Venus. Researchers have discovered unexpected patterns of slow motion and abundant stationary waves in Venus's nighttime sky. […]

  • Astronomer searches for signs of life on Wolf...
    on January 19, 2017 at 9:15 pm

    Astronomers have located the habitable zone, the region where water could exist on the surface of a planet, on the Wolf 1061, a planetary system that's 14 light years away. […]

    The European Space Agency's Venus Express mission has provided a great amount of data from the surface and atmosphere of Earth's inner twin planet. Among these observations was the mapping of the southern hemisphere of Venus in the near infrared spectral range. However the thick and permanent cloud cover of Venus limits the achievable resolution, similar to observing a scene through fog. Using a numerical model, planetary researchers pushed the limits of the data resolution. […]

  • How Earth sheds heat into space
    on September 24, 2018 at 7:00 pm

    Just as an oven gives off more heat to the surrounding kitchen as its internal temperature rises, the Earth sheds more heat into space as its surface warms up. Since the 1950s, scientists have observed a surprisingly straightforward, linear relationship between the Earth's surface temperature and its outgoing heat. […]

  • Three NASA missions return first-light data
    on September 21, 2018 at 5:44 pm

    NASA's continued quest to explore our solar system and beyond received a boost of new information this week with three key missions proving not only that they are up and running, but that their science potential is exceptional. On Sept. 17, 2018, TESS—the Transiting Exoplanet Survey Satellite—shared its first science observations. Later in the week, the latest two missions to join NASA's heliophysics fleet returned first light data: Parker Solar Probe, humanity's first mission to […]

    on September 19, 2018 at 1:31 pm

    A month before the planned launch of the joint ESA-JAXA BepiColombo mission to Mercury, two new studies shed light on when the innermost planet formed and the puzzle of its chemical composition. The findings will be presented by Bastien Brugger and Thomas Ronnet at the European Planetary Science Congress (EPSC) 2018 in Berlin. […]

  • Closest planet ever discovered outside solar...
    on September 17, 2018 at 2:07 pm

    In August of 2016, astronomers from the European Southern Observatory (ESO) confirmed the existence of an Earth-like planet around Proxima Centauri – the closest star to our solar system. In addition, they confirmed that this planet (Proxima b) orbited within its star's habitable zone. Since then, multiple studies have been conducted to determine if Proxima b could in fact be habitable. […]

    Gearing up for its first flight test, NASA's Adaptable Deployable Entry Placement Technology, or ADEPT, is no ordinary umbrella. ADEPT is a foldable device that opens to make a round, rigid heat shield, called an aeroshell. This game-changing technology could squeeze a heat shield into a rocket with a diameter larger than the rocket itself. The design may someday deliver much larger payloads to planetary surfaces than is currently possible. […]
