Is there an ancient black hole at the edge of the solar system? –Hints of a hefty source of gravity beyond Pluto sparked the search for a possible "Planet Nine". Now, some astronomers think it could instead be a black hole from the big bang, offering a rare glimpse into the early universe, reports New Scientist.
Other things going on recently:
MADAGASCAR: GES to install a hybrid solar system at the Ambokatra quarry | Afrik 21
Mobile electricity production units will soon be installed at Ambokatra, the main quarry supplying building materials in Madagascar. This is the aim of an agreement recently signed between Colas Madagascar and Green Energy Solutions (GES), a joint venture between the Axian group and the energy company GreenYellow. As part of this project, which is now underway, GES will install a power plant consisting of solar panels and two fully equipped containers.
For Christian Cachat, GES’ Managing Director, this is a “technically ambitious project, which will have a significant impact in terms of carbon savings and operating comfort. It will be the first modular industrial hybrid solar power plant that allows us to commit to a medium-term contract and whose installations can be redeployed. This is, for me, the real innovation of this project.
Borisov comet 'most pristine' object from outer space seen in Solar System - Science & Tech -
This handout image made available on March 30, 2021 by the European Southern Observatory shows the comet 2I/Borisov passing near the Sun taken with the FORS2 instrument on ESO's Very Large Telescope in late 2019. Since the comet was travelling at breakneck speed, around 175 000 kilometres per hour, the background stars appeared as streaks of light as the telescope followed the comet's trajectory.
A newly observed interstellar comet is the most pristine visitor from outer space ever seen in our Solar System, according to a pair of studies released Tuesday detailing its unique characteristics.
NASA's Europa Clipper Builds Hardware, Moves Toward Assembly
NASA's Europa Clipper, depicted in this illustration that was updated in December 2020, will swoop around Jupiter on an elliptical path, dipping close to its moon Europa on each flyby to collect data.
Technicians and engineers at NASA's Jet Propulsion Laboratory work together on Sept. 12, 2019, to bond thermal tubing to a panel built for NASA's Europa Clipper spacecraft by the Johns Hopkins University Applied Physics Laboratory (APL). The tubing controls the orbiter's temperature as it travels.
Quite a lot has been happening:
Roman Telescope Predicted to Find 100,000 Transiting Planets – Exoplanet Exploration: Planets
NASA’s Nancy Grace Roman Space Telescope will create enormous cosmic panoramas, helping us answer questions about the evolution of our universe. Astronomers also expect the mission to find thousands of planets using two different techniques as it surveys a wide range of stars in the Milky Way.
Scheduled for launch in the mid-2020s, Roman will be one of NASA’s most prolific planet hunters.
The mission’s large field of view, exquisite resolution, and incredible stability will provide a unique observational platform for discovering the tiny changes in light required to find other worlds via microlensing . This detection method takes advantage of the gravitational light-bending effects of massive objects predicted by Einstein's general theory of relativity.
Interstellar visitor Borisov could be 1st truly pristine comet yet seen | Space | EarthSky
Comet 2I/Borisov is the 2nd known object to pass near our sun from outside our solar system. Its 2019 pass near our sun might have been its first-ever interaction with a star. If so, it’s among the most pristine, or unspoiled, objects yet known.
Bagnulo led a new study on Comet 2I/Borisov, published March 30, 2021, in the peer-reviewed journal Nature Communications .
For the first time, scientists find X-rays coming from Uranus
The study published in the Journal of Geophysical Research on Wednesday examined two visuals of the planet taken by the Chandra Observatory in 2002 and 2017. The first observation revealed a clear detection of X-rays, and the second revealed a possible flare of X-rays on the ice giant, a planet mainly composed of elements heavier than hydrogen and helium.
But, the agency said, "there are tantalizing hints that at least one other source of X-rays is present."
Making a solar water heater for the home
Q: We have a large family and use much hot water. I cannot afford to have a solar water heating system installed, but I would like to make some type of solar water heater myself. What do you suggest?
A: Heating your domestic hot water is an excellent application for solar energy. Unlike solar space heating, water heating is needed year-round. This provides a good payback, especially if you build it yourself and must only cover material costs.
Your first step is reducing the amount of hot water consumed. With a large family, much of the hot water usage is for showering. Unlike clothes or dishwashing where the amount of hot water used is set by the appliance, you can modify showering to save much hot water.
