Spica is the brightest star in the constellation of Virgo (lower left). As one of the nearest massive binary star systems to the Sun, Spica has been the subject of many observational studies. [17] Spica is believed to be the star that gave Hipparchus the data that led him to discover the precession of the equinoxes. [18]
To find this star easily, locate the Big Dipper and follow the curve of its handle. This curve will first lead to Arcturus. Finally, "drive a spike" directly to Spica. [16] The constellation of Virgo. Spica is made up of two individual stars, Spica A and Spica B, with radii of 7.40 and 3.64 times the Sun's, respectively. [17]
The bright star Spica makes it easy to locate Virgo, as it can be found by following the curve of the Big Dipper/Plough to Arcturus in Boötes and continuing from there in the same curve ("follow the arc to Arcturus and speed on to Spica").

To find the moon’s height in Tallahassee at the solstice, subtract from Tallahassee’s latitude 23.5 degrees (30 - 23.5 = 6.5 degrees). ... Moon near bright star Spica in Virgo in the morning sky.
The Space Infrared Telescope for Cosmology and Astrophysics (SPICA), was a proposed infrared space telescope, follow-on to the successful Akari space observatory. It was a collaboration between European and Japanese scientists, which was selected in May 2018 by the European Space Agency (ESA) as a finalist for the next Medium class Mission 5 (M5) of the Cosmic Vision programme, to launch in ...
Prominent examples of stars in this mass range include Antares, Spica, Gamma Velorum, [2] Mu Cephei, and members of the Quintuplet Cluster. [3] Type Ia supernova progenitors are white dwarf stars that are close to the Chandrasekhar limit of about 1.44 solar masses and are accreting matter from a binary companion star.
In 2014, Copenhagen Suborbitals designed a basic first crewed rocket and space capsule. They named it Spica, and it is planned to stand 12–14 m tall with a diameter of 950 mm. [11] As of late September 2024, two pressure hardened 950mm steel tanks have been constructed and the development of the BPM-25 engine class is well underway.
