  • NASA’s Curiosity rover confirmed the presence of Methane in Mars
    NASA has confirmed that the Curiosity rover, the NASA’s Mars Science Laboratory mission, recently detected the largest amount of methane ever measured during the mission. Curiosity’s methane reading came to 21 parts per billion units by volume. It is thrice the amount it sniffed out during a surge in 2013.

    During a follow-up test later, though, scientists found that the methane levels around the rover already dropped sharply. Curiosity detected normal methane levels, that is 1 part per billion by volume, following the sudden elevation. It suggested that the abnormally high values came from transient methane plumes.

    As Curiosity is not equipped with instruments to determine whether the source of methane is biological or geological, the scientists are yet to figure out a pattern for Martian’s transient plumes.

    The scientists plan to gather more information through Curiosity and from other missions to gain a deeper understanding of the plumes. The scientist will be able to understand whether the presence of methane on the red planet truly is a sign of life only if they finds where the plumes are coming from.

  • World Oceans Day is celebrated on 8th June
    World Oceans Day is celebrated on 8th June every year. The day was declared in 2008. June 8 was marked as it marks the day when it was first proposed in 1992 by Canada's International Centre for Ocean Development (ICOD) and the Ocean Institute of Canada (OIC) at the Earth Summit, UN Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil

    The Conference supported the implementation of Sustainable Development Goal (SDG) 14 of the 2030 Agenda for Sustainable Development: Conserve and sustainably use the oceans, seas and marine resources for sustainable development.

    The theme for the year 2019 is Gender and Oceans. The theme is to build greater ocean and gender literacy and to discover possible ways to promote gender equality in ocean-related activities such as marine scientific research, fisheries, labour at sea, migration by sea and human trafficking, as well as policy-making and management.

    The importance of gender equality is being recognized increasingly for the effective conservation and sustainable use of oceans, seas, and marine resources. Yet very little data and researches are available on these issues. Serious action towards gender equality and the empowerment of women and girls is still needed in all ocean-related sectors to achieve Sustainable Development Goal .
