NASA's Spitzer telescope completes 15 yrs in space
Washington, Aug 26: NASA's Spitzer Space Telescope, the youngest member of the "Great Observatory" programme, has completed 15 years in space.
The Great Observatories are four big-ticket space telescopes -- Spitzer, Hubble Space Telescope, the Compton Gamma Ray Observatory (CGRO), and the Chandra X-ray Observatory -- designed to view the universe in different and complementary wavelengths of light.
Launched into solar orbit on August 25, 2003, Spitzer was initially scheduled for a minimum 2.5-year primary mission. But the space telescope has lasted far beyond its expected lifetime, the US space agency said in a statement.
"In its 15 years of operations, Spitzer has opened our eyes to new ways of viewing the universe," said Paul Hertz, director of the Astrophysics Division at NASA Headquarters in Washington.
"Spitzer's discoveries extend from our own planetary backyard, to planets around other stars, to the far reaches of the universe. And by working in collaboration with NASA's other Great Observatories, Spitzer has helped scientists gain a more complete picture of many cosmic phenomena," he added.
Celebrating Spitzer's incredible discoveries and amazing images, NASA has also released two new multimedia products: The NASA Selfies app for iOS and Android, and the Exoplanet Excursions VR Experience for Oculus and Vive, as well as a 360-video version for smartphones, the statement said.
Spitzer has logged over 106,000 hours of observation time in the past 15 years.
It has illuminated some of the oldest galaxies in the universe, revealed a new ring around Saturn, and peered through shrouds of dust to study newborn stars and black holes.
The space telescope also assisted in the discovery of planets beyond our solar system, including the detection of seven Earth-size planets orbiting the star TRAPPIST-1, among other accomplishments.
Spitzer orbits the Sun in an Earth-trailing orbit (meaning it literally trails behind Earth as the planet orbits the Sun) and has continued to fall farther and farther behind Earth during its lifetime.
In 2016, Spitzer entered an extended mission dubbed "Spitzer Beyond". The spacecraft is currently scheduled to continue operations into November 2019, more than 10 years after entering its warm phase, the statement noted.

UP Police use tear gas to disperse crowd throwing stones during Sambhal mosque survey
Sambhal (UP) (PTI): Police used tear gas and "minor force" in the face of stone pelting by locals here on Sunday as tension escalated during a second survey of the Mughal-era mosque, claimed to be originally the site of an ancient Hindu temple.
Tension has been seething in Sambhal over the past few days after the Jama Masjid was surveyed last Tuesday on the orders of a local court following a petition that claimed that a Harihar temple stood at the site.
According to the local administration, a second survey by an "Advocate Commissioner" as part of a court-ordered examination into the disputed site began around 7 am and a crowd began gathering at the spot.
"Some miscreants came out of the crowd gathered near the site and pelted stones at the police team. The police used minor force and tear gas to bring the situation under control," Superintendent of Police Krishna Kumar Vishnoi said.
He said those who engaged in stone pelting and those who incited them will be identified and action taken against them.
District Magistrate Rajendra Pesia said, "Some miscreants resorted to stone pelting but the situation is peaceful now and the survey is underway."
Videos of youths throwing stones at police, purportedly near the site of the survey in Sambhal have surfaced on the Internet.
Supreme Court lawyer Vishnu Shankar Jain, who is also the petitioner in the case, had said the Court of Civil Judge (Senior Division) ordered the constitution of an "Advocate Commission" to survey the mosque.
The court has said that a report should be filed after conducting a videography and photography survey through the commission, he had said.
The Central and Uttar Pradesh governments, the mosque committee and the district magistrate of Sambhal have been made parties in the petition concerning the mosque, Jain said last Tuesday.
Vishnu Shankar Jain and his father Hari Shankar Jain have represented the Hindu side in many cases related to places of worship, including the Gyanvapi Mosque-Kashi Vishwanath temple dispute.
Gopal Sharma, a local lawyer for the Hindu side, told PTI on Friday that in his petition filed in the court, he mentioned that "Baburnama" and the "Ain-e-Akbari" has confirmed that a Harihar temple was at the site where the Jama Masjid now stands.
He also claimed that the temple was demolished by Mughal Emperor Babur in 1529.
Samajwadi Party (SP) MP Zia Ur Rehman Barq had objected to the developments.
"The Jama Masjid of Sambhal is historical and very old. The Supreme Court had given the order in 1991 that whatever religious places are there in whatever condition since 1947, they will remain at their places," he had said.
The next date for hearing in this case is January 29.
