Components of the induced magnetosphere are shown. Venus is known not to have a magnetic field. [46] [47] The reason for its absence is not at all clear, but it may be related to a reduced intensity of convection in the Venusian mantle. Venus only has an induced magnetosphere formed by the Sun's magnetic field carried by the solar wind. [46]
The USGS Branch of Astrogeology [9] has produced full resolution radar maps (also known as FMAPs) of Venus from the SAR data collected from the mission, called the Magellan F-BIDRs (Full resolution Basic Image Data Records). The maps have a coverage of around 92% (combination of the 2 left-looking cycles).
A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1] [2] It is created by a celestial body with an active interior dynamo.
Venus lacks an internal dynamo, and its weakly induced magnetosphere is caused by atmospheric interactions with the solar wind. Internal heat escapes through active volcanism, [21] [22] resulting in resurfacing instead of plate tectonics. Venus is one of two planets in the Solar System, the other being Mercury, that have no moons. [23]

"Venus now has surface conditions that are extreme compared to Earth, with an atmospheric pressure 90 times greater, surface temperatures soaring to around 465°C (869°F), and a toxic atmosphere ...
The Venus Emissivity Mapper (VEM) is a spectrometer for mapping the surface composition of Venus through a distinct number of atmospheric spectral windows. It will be one of the two payloads onboard the VERITAS mission, and will also be the VenSpec-M channel of the EnVision mission's spectrometer suite.
Cold brew coffee is made from coffee grounds steeped in cold or room temperature water for at least 12 hours, “creating a mellower, smoother beverage,” as TODAY.com previously reported.
