New Tool Developed by Astronomers to Remove Satellites’ Effects on Hubble Images

With increasing numbers Satellites In the sky, astronomers have repeatedly expressed concern about how these satellites may affect scientific research, and earlier this year.

A study of Hubble Space Telescope observations showed how some images were destroyed by streaks of light coming from satellites – and while only a small percentage of Hubble images were affected, the authors raised concerns that with the number of satellites expected to explode in the next decade the problem could become serious.

Dave Stark of STScI said in a statement, astronomers at the Space Telescope Science Institute (STScI), which now runs Hubble, have come up with a tool to manipulate satellite lines in Hubble images.

We have developed a new satellite trajectory tool that is an improvement over previous satellite programs because it is much more sensitive. So we think it would be better to locate and remove satellite tracks in Hubble images.”

The tool works by looking for trails in images from one of Hubble’s cameras, the Advanced Camera for Surveys. This camera has a very wide field of view, which means that it captures a large portion of the sky at once. This is useful in this case because it means that the tracks from the satellites will cross a very small percentage of the image.

According to the forecasts of the National Meteorological Service (SMN)there are three phenomena that will cause heavy rains in at least nine states of the Mexican Republic. These are low pressure channels, the Cold Front number 3 and the entry of humidity from the Pacific Ocean which will generate very heavy rains in Campeche, Chiapas, Quintana Roo and Yucatán; strong in Chihuahua, Durango, Jalisco, Nayarit and Sinaloa. Showers will occur in Coahuila, Colima, Guerrero, Michoacán, Oaxaca, Tabasco and Veracruz, and isolated rains in the State of Mexico, Hidalgo, Nuevo León, Puebla, San Luis Potosí and Tamaulipas. Take your precautions because heavy rainfall could generate landslides, increases in the levels of rivers and streams, overflows and floods, so the population is recommended to follow the instructions of Civil Protection. Likewise, wind streaks of 60 to 70 kilometers per hour (km/h) are estimated with conditions for the formation of whirlwinds or tornadoes in Chihuahua and Coahuila; streaks of 40 to 60 km/h in the Isthmus of Tehuantepec, and with possibility of tornadoes in Aguascalientes, Baja California, Baja California Sur, Mexico City Durango, Mexico State, Guanajuato, Hidalgo, Jalisco, Nuevo Leon, Puebla, Queretaro , San Luis Potosí, Sonora, Tamaulipas, Tlaxcala and Zacatecas.
